INTRODUCTION - Honours 2020 This booklet is intended to provide an overview of the research activities within the School of Chemistry and to give you an indication of the Honours projects that will be offered in 2020. You are encouraged to study these and to speak with the research supervisors. This research project makes up 75% of the final mark for the Honours year, with the other 25% from the coursework component which runs in first semester. Current third year students are eligible to do Chemistry Honours (Clayton) in 2020 provided that they fulfil the entry requirements and that a supervisor is available. Students will be allocated to supervisors and projects on the basis of their third year results and their preferred projects. Great care is taken to ensure that all students are treated equitably and where possible that they are be allocated to the area and supervisor of their choice. All Honours candidates must discuss prospective projects with at least four supervisors before choosing their preferred project. They should then select at least three potential supervisors and projects in order of preference. The application forms – one for Honours entry which is an on-line link from the Faculty of Science, the other is the project nomination form which is from the School of Chemistry – are both available on the School of Chemistry Honours web page. Please note that the project descriptions are quite short, and more comprehensive details can be obtained when speaking to supervisors. We look forward to seeing you in the Honours course next year. Please contact me if you have any questions about the Honours year! Assoc. Prof Mike Grace Honours Coordinator Room G25c/19 School of Chemistry, 9905 4078, email: Michael.Grace@monash.edu 3
Professor Phil Andrews Room No. 121N, Tel: 9905 5509, email: phil.andrews@.monash.edu This document gives you an idea of the type of research we are undertaking within my group. If you have any further queries, please do not hesitate to contact me (details above). More information on my research can be seen at: http://monash.edu/science/about/schools/chemistry/staff/Andrews.html 1. Combating multi-drug resistant bacteria with metal complexes (Bi vs Fe vs Ga) (with Prof. Ross Coppel, Microbiology) In tackling the continued growth in multi-resistant bacteria and the increasing rate of antibiotic resistance, this project focuses on the development of bismuth(III) and gallium(III) compounds which show high activities against common and resistant strains of bacteria (eg MRSA, VRE). Read more: Chem. Eur. J., 2014, DOI: 10.1002/chem.201404109. 2. Development of new bismuth and gallium based anti-Leishmanial drugs (with Dr Lukasz Kedzierski, Peter Doherty Institute, University of Melbourne) Leishmaniasis is a parasitic infection prevalent in the developing world. Current frontline drugs are based on Sb(V) compounds which show severe side-effects and for which resistance has begun to appear. This project focuses on developing and testing new bismuth and gallium compounds as more active and less toxic alternatives. Read more: Dalton Trans., 2018, 47, 971 – 980. DOI: 10.1039/C7DT04171C 3. Developing new antimicrobial materials and coatings (with Dr. Warren Batchelor, Chemical Engineering; Prof. Laurence Meagher, Monash Institute of Medical Engineering) This project investigates the formation of novel bismuth(III) complexes which have high antimicrobial activity and their incorporation into natural and synthetic polymers and materials. The antimicrobial activities of the new materials and their potential as ‘clean surfaces’ will be assessed. Read more: Chem. Eur. J., 2018, 24, 1 – 13. DOI: 10.1002/chem.201801803 4. Targeting Novel Chiral Heterobimetallic Main Group Complexes (with Dr. Victoria Blair) This project involves the design, synthesis and full characterization of novel chiral hetero-di-anionic and hetero-bimetallic complexes of alkali metal, and d or p-block elements (eg. Zn, Cu, Al, Ga, In, Sn, Sb), and subsequent examination of their reactivity and selectivity in asymmetric synthesis and in the formation of unusually substituted heterocycles. Requires inert atmosphere handling techniques. Read more: Organometallics, 2018, 37, 1225–1228. DOI: 10.1021/acs.organomet.8b00047 5. Heterobimetallic Compounds, Cages and Nanoparticles for Radiation Sensitisation (with Dr Melissa Werrett; Prof Leoni.Kunz-Schughart, National Center for Radiation Research in Oncology, TU-Dresden) Radiation therapy (RT) is a common form of cancer treatment, however the resistance of tumour cells to RT is a serious concern. One way to enhance damage to tumour cells is to employ radio- sensitisers. These are molecules, cages or nanoparticles which can increase the radio- sensitivity of tumour cells and therefore the effectiveness of the treatment. This project will explore the design and development of mixed heavy metal compounds and an assessment of their potential as radio-sensitisers for tumour cell depletion.

Professor Stuart Batten Room No. 121C, Building 19, Tel: 9905 4606, email: stuart.batten@monash.edu This document will give you an idea of the type of research we are undertaking within my group. If you have any further queries, please do not hesitate to contact me (details above). More information on my research can be seen at: http://monash.edu/science/about/schools/chemistry/staff/sbatten/index.html Coordination Polymers and Supramolecules We are designing and making coordination polymers (sometimes also known as metal-organic frameworks, or MOFs) and supramolecular species for a variety of interesting applications, including adsorption of gases such as hydrogen (for hydrogen fuelled cars) and carbon dioxide (greenhouse gas capture), long or short range magnetic ordering, molecular switching (for information storage or molecular sensing), and as new materials for molecular separations. We are pursuing a number of approaches to this, including: • New classes of bridging ligands in which the bridging length can be controlled by the presence or nature of e.g. group I or II metals (Chem. Commun., 2009, 5579). • Large (3 nm in diameter) spherical supramolecules (or ‘nanoballs’) (Angew. Chem. Int. Ed. 2009, 48, 2549 & 8919; ChemPlusChem 2012, 77, 616) which show a large variety of properties. For example, they can switch between two magnetic spin states. The change may be induced by change in temperature or, as a series of experiments in Bordeaux, France showed, irradiation of light. The molecular packing also creates cavities within the solid state, and thus the crystals will readily absorb solvent vapours, hydrogen, and CO2. Finally, the nanoballs also show catalytic activity. • Incorporation of amine groups into porous MOFs in order to increase the selectivity of CO2 sorption over other gases, such as N2. This is part of a large multi-institutional program focussed on developing MOFs for “real world” CO2 capture. • Porous MOFs for the chromatographic separation of molecules based on size, chirality or other chemical features. Surprisingly little work has been done in this field, and we are currently exploring this potential in depth (Chem. Commun. 2014, 50, 3735). Chemistry of Small Cyano Anions We have been investigating the chemistry of small cyano anions (Chem. Commun. 2011, 47, 10189). They have shown some remarkable chemistry, including the synthesis of a large range of transition metal and/or lanthanoid clusters which may have applications as single molecule magnets, interesting new coordination polymers and discrete complexes showing unusual packing motifs and ligand binding modes, new hydrogen bonding solid state networks, nucleophilic addition of alcohols and amines across the nitrile groups to give new anion families, and the production of ionic liquids containing either the free anions or even metal complexes of the anions. The versatility and range of applications of these simple anions is unprecedented. 5
Dr Toby Bell Room G32C, Building 23S, Tel: 69905 4566, email: toby.bell@monash.edu In the Bell Fluorescence Lab, we apply advanced fluorescence techniques to answer questions in materials science and cell biology. In most of our research we operate at the ultimate level of resolution – single molecules – which allows us to detect hidden events and distributions. Application of single molecule detection allows us to perform super-resolution imaging and break the diffraction limit of light to reveal previously obscured details, even inside cells. www.super-resolution.org.au Instagram: Bell_Fluorescence Visualising cellular remodelling caused by viral proteins: Viruses have developed all kinds of mechanisms for hijacking cellular systems for their own needs, as well as for avoiding the immune response. This project will use super-resolution imaging to examine changes to the cellular architecture in order to decipher the functions of proteins made by viruses like Rabies and Hendra. (The image shows microtubules forming 2 μm large bundles in the presence of rabies P protein) Deciphering the photophysics of antibody-conjugated fluorophores for bio-imaging: Alexa and ATTO dyes bound to antibodies are used extensively in biological imaging applications because of their high specificity and bright, stable fluorescence. Recently, the seconds-long ‘blinking’ of these dyes has been harnessed for super resolution imaging. While the photophysics behind blinking has been well characterized for individual molecules, this project will investigate the photophysical interactions available, such as energy funnelling and annihilation, to the clusters of ~4- 6 fluorophores on each antibody. Investigating DNA damage response in sub-nuclear compartments: When the cell senses a DNA double strand break, a signaling cascade involving thousands of proteins is triggered. Recently, a new pathway within this cascade was discovered to involve recruitment of protein NBS1 to the nucleolus where it affects ribosomal RNA transcription. This project will use super-resolution imaging to directly visualize the proteins involved in nucleolar sub-compartments to determine the underlying mechanism and its interplay with other DNA damage response pathways. (The image shows Treacle protein ‘puncta’ inside the nucleolus) Imaging DNA double strand breaks and their repair in cells: DNA damage is caused by exogenous toxins as well as everyday replication and transcription. Defects in repair result in serious genetic diseases and can lead to cancer. However, imaging of damage and repair inside cells is incredibly difficult because only a few breaks occur at a time. This project will use multicolor super resolution imaging to focus on these few breaks and track the temporal interactions involved in their (mis)repair.. Quantifying orientation in FRET at the single molecule level: The orientation of the donor and acceptor molecules in energy transfer (FRET), can efficiency up to a factor of 4, but has never been shown directly in single molecules. This project will visualize emission dipoles of single molecules undergoing FRET by using ‘defocused imaging’ of single molecules and simultaneously measuring FRET efficiency. The defocused images reveal a molecule’s dipole directly and thus its orientation. (The image shows defocused patterns for 2 single molecules about 3 microns apart) 6

Professor Alan Chaffee Room No. 223N, Building 23, Tel: 9905 4626, email: alan.chaffee@monash.edu My group undertakes applied chemistry research on topics that are, in some way, related to biomass and fossil fuel utilization. For example, new approaches to the preparation of industrial chemicals, specialty liquid fuels (eg, jet fuel), road bitumen, coke for steel making, and specialist high surface area active carbons are being developed so as to minimize energy losses and CO2 emissions. We also investigate the capture of CO2 emissions by adsorption and, once captured, its transformation back into useful products by heterogeneous catalysis. In doing so, innovative new materials such as mesoporous silicas, metal organic frameworks (MOFs) and ionic liquids (ILs) are employed as adsorbents, catalysts and/or solvents. These novel materials are often sourced from other research groups within the School. Molecular modeling tools are also frequently applied in these studies, so that experiment and theory inform each other. More information on my research can be found at: http://monash.edu/science/about/schools/chemistry/staff/CHAFFEE.html Turning Carbon Dioxide into Fuel Waste CO2, when combined with ‘renewable H2‘ (eg, from photovoltaic water splitting) over appropriate catalysts, leads to reduced C1 products (formaldehyde, methanol). Methanol can be used directly as fuel in petrol engines or be dehydrated to dimethylether, a diesel fuel substitute. Nanoparticulate catalysts of varying metal cluster size, supported on high surface area mesoporous substrates, will be sought that improve reaction rates and product selectivity. . Chemicals from Biomass This project will make use of CO2, both as a supercritical fluid in its own right and as one component of a novel series of recyclable ionic liquids (known as DIMCARBs) to selectively extract discrete chemical classes (phenols, carboxylic acids, aliphatic or aromatic hydrocarbons, depending on the conditions used) from various forms of biomass and/or coal. With biomass, this approach offers a renewable alternative to deriving these fundamental chemical feedstocks that are now mostly supplied from the petroleum industry. Capturing Carbon Dioxide from Air Prior work in the group has identified amine-based adsorbents that have the ability to reversibly capture and release CO2 at concentrations (~15 wt%) and temperatures typical of the flue gas from power stations. Another approach to controlling CO2 in the atmosphere could be to adsorb it directly from air at atmospheric concentration (~400 ppm). This project will prepare and evaluate new adsorbent formulations for this purpose involving high surface area mesoporous silica (such as SBA-15) as a support material. Environmental Applications of Active Carbon Monoliths The group has recently developed a new form of monolithic carbon that provides for efficient gas and liquid contact with low pressure drop. These materials have exceptional surface areas and, therefore, multiple potential applications as adsorbents, catalysts, electrodes, etc. Their inherent electrically conductive means that they can, in principal, be very efficiently regenerated by ohmic heating. Projects are available that investigate their performance for the removal of pollutants from gas phase (e.g., NOx) or from liquid phase (e.g., heavy metal) streams, their regenerability, as well as optimization of fabrication methods.

Synthesis 2018, 1402. –H + Organocatalysis: Unleashing the Enantioselective Potential of Chiral Brønsted Acids One of the most powerful catalytic methods to emerge over the last two decades to rapidly achieve molecular complexity in an enantioselective manner from readily accessible precursors is organocatalysis. Our interest in the organocatalytic reaction chemistry of -rich alcohols is driven by the ease of substrate preparation providing the possibility to introduce a wide variety of substituents. Added to this is the potential formation of water as the only byproduct that makes it a highly attractive environmentally sustainable and atom-economical approach.

Associate Professor Perran Cook Room No. 19/G25a, Tel: 9905 54091, email: perran.cook@.monash.edu More information on my research can be seen at: http://monash.edu/science/about/schools/chemistry/staff/cook/ Sand sediments dominate our coastline, yet we have little understanding of how this environment processes human emissions of nutrients. Novel metabolic pathways of lipid and hydrogen production in sands Sands are highly dynamic environments and organisms within this environment must cope with rapid shifts between oxic and anoxic conditions. We have recently discovered that fermentation dominates anoxic metabolism in these sediments but the pathways remain unknown. We hypothesise that a carbon storage mechanism using polyhydroxyalkanoates is taking place. This project will investigate the pathways of microbial metabolism in sands using a combination of experiments and metabolite profiling using GC/MS Figure shows oxygen distribution within a sand ripple. Organisms within this environment must cope with rapid shifts in oxygen concentrations. Denitrification in sands Denitrification is a key reaction in the environment because it removes excess bioavailable nitrogen. The reaction is typically considered a heterotrophic process where organic carbon acts as the electron donor. 4NO3- + 5CH2O 2N2 + 4HCO3- + CO2 + 3H2O Our recent research has discovered that H2 and FeS may also act as electron donors in sand sediments however the relative importance of these remains unknown. This project will investigate the importance of H2 and FeS as electron donors for denitrification. 10
Professor Glen Deacon Room No. 136C, Building 19 Tel: 9905 4568, email: glen.deacon@monash.edu For more information, see: www.chem.monash.edu.au/staff/deacon.html Rare earth elements (Group 3-Sc, Y, La and the lanthanoids Ce - Lu) Rare earths are currently seen as the strategic materials of the 21st century with considerable international concern over the Chinese domination of the supply of separated elements. Our group provides fundamental knowledge to underpin industrial developments in the area. Australia has abundant rare earth resources which have been mainly neglected despite their widespread uses, e.g. ceramic supports for exhaust emission catalysts, alloy magnets in all car engines, and catalysts for artificial rubber production. Potential applications include green corrosion inhibitors (below). Their metal- organic chemistry is a major new frontier and is generating great excitement, for example in the discovery of new oxidation states. We are particularly interested in high reactivity rare earth organometallics (Ln-C), organoamides (Ln-NR2) and aryloxides (Ln-OAr), and have developed unique synthetic methods to obtain them. Features of these compounds include low coordination numbers and extraordinary reactivity including C-F bond activation, the most resistant carbon-element bond. To prepare and structurally characterize the compounds represents a major challenge. The program involves extensive international collaboration. Some specific projects follow: 1. New Approaches to Metal-Based Syntheses (with Prof. Peter Junk (JCU) and Dr Victoria Blair) 2. Carbon-fluorine activation with reactive rare earth complexes (with Dr Victoria Blair and Prof Peter Junk) 3. Heterobimetallic complexes and pseudo solid state synthesis (with Prof. Peter Junk (JCU) and Dr David Turner) 4.

Dr Alison Funston Room No. G32B, Tel: 9905 6292, email: alison.funston@monash.edu https://funstongroup.monash.edu/ Description of Project Areas When matter is divided into tiny, tiny particles, that is, into crystals of nanometer sizes (1 nm = 1 10-9 m), its properties change. We are interested in the changes to the optical properties, or colour. For example, very tiny spheres containing only 1000’s of gold atoms are red. The colour of very tiny spheres of CdSe only a few nanometers in diameter can be tuned across the visible region by changing their size. This effect is due to quantum confinement and the spheres are called quantum dots (QDs). The colours of nanoparticles can be controlled by: Changing the size or shape of the crystal Changing the environment of the crystal Bringing two or more nanocrystals into close proximity The nanocrystals have potential applications in nanoscale energy transfer, sensing, colour responsive coatings for glass, solar photovoltaics and medicine (drug delivery, cancer therapies). Our research group is part of the ARC Centre of Excellence in Exciton Science. The Centre researches ways to manipulate the way light energy is absorbed, transported and transformed in advanced nanoscale materials. The research in the centre aims to find innovative solutions for renewable energy in: Solar energy conversion Energy-efficient lighting and displays Security labelling and optical sensor platforms Our research involves synthesis and investigation of the optical properties of nanocrystal systems. We investigate the mechanism of growth of nanocrystals, making use of electron microscopy (TEM and SEM). We use dark-field microscopy, fluorescence microscopy, single photon counting and scanning near-field optical microscopy to determine the optical properties of single nanoparticles and single nanoparticle superstructures. Potential honours project titles include: Controlling the Flow of Energy on the Nanoscale: Investigation of the control of light (energy) transport through nanoscale structures, including switching transport on or off, energy and electron transfer between nanocrystals, across interfaces and within self-assembled films. Changing the Colour of Nanoparticles - Nanoparticle Coupling: Assemblies of nanocrystals have optimal characteristics for many applications. This project aims to make, understand and use these. Nanoparticles and Nanowires as Nanoscale Optical Fibres: Nanowires are able to transport energy below the diffraction limit of light. This project will investigate how the three-dimensional shape of the nanowire changes the efficiency of the energy transport. Growth Mechanism of Nanorods and Nanobars (including Nanoscale Gold Bullion!): Understanding nanocrystal growth, the ultimate form of crystal assembly, will allow fine control of the nanocrystal optical properties – many questions remain unanswered! 12
Associate Professor Mike Grace Room No. G25c (Water Studies), Tel: 9905 4078, email: michale.grace@monash.edu These projects can be modified to suit the interests of the student – from physical, analytical and/or environmental chemistry and biogeochemistry through to aquatic and/or restoration ecology. A project is available for students who wish to combine synthetic and environmental chemistry. Assessing the impacts of pharmaceuticals on aquatic ecosystem processes Awareness of the effects of common pharmaceuticals on organisms (insects, fish) living in streams and lakes has slowly emerged over the last decade. Despite their prevalence in urban waterways, there has been almost no published research on how these pharmaceuticals can affect rates of fundamental ecosystem processes. Work in our group has shown that some of these chemicals can have dramatic effects. This project will use novel pharmaceutical diffusing substrates and bioassay techniques to investigate effects of common drugs like antibiotics, mood modifiers, painkillers and antihistamines on a range of fundamental ecosystem processes including photosynthesis, respiration, biomass accrual and denitrification in urban waterways. Constructed wetlands – environmental benefactors or villains? This project will examine the extent to which wetlands around Melbourne generate greenhouse gases (GHGs) including CH4, N2O and CO2. The prevailing wisdom is that wetlands must be beneficial for the environment as they are designed to remove nutrients and other pollutants from stormwater in urban creeks. However, previous work in the Water Studies Centre has shown that under a range of relatively common conditions, wetlands can also generate significant quantities of GHGs. This project will measure rates of GHG production in several wetlands around Melbourne and develop understanding of the key wetland characteristics and conditions that control production. Links with nitrogen cycling will be explored. Experimental work will involve field measurements and laboratory mesocosm (sediment core) investigations.

Dr Joel F. Hooper Room No. 242, Building 23 South, Tel: 9902 0482, email: joel.hooper@monash.edu Our group is focused on the development of new catalytic reactions, using both organic and organometallic catalysts. We examine novel catalysts and/or new reaction intermediates to develop new chemistry for a variety of applications. Catalytic reactions with new metal complexes We have recently reported the first catalytic application of a monomeric Pd(I) species, in the oxidative cross- coupling of nucleophiles.1 We are targeting new reaction pathways which make use of this unexplored oxidation state of palladium. We are also interested in developing catalytic reactions of ruthenium carbides, a complex with unique reactivity that has yet to be harnessed in catalysis. This project will access new carbine chemistry using these complexes, and combine it with established alkene metathesis chemistry to deliver new organic reactions. Organocatalytic synthesis of morphine In a collaboration with the Lupton group,2 we have developed phosphine catalysed methods for the construction of 5- and 6-membered nitrogen heterocycles. In this project, we will look to develop one of these reactions for the total synthesis of morphine and related alkaloids. Chemical modification of polymers We have developed a method for the end-group modification of RAFT polymers, which allows us to attach functional materials to polymers.3 With collaborators in Monash Medicine, we are developing polymer/antibody hybrids which will be used to treat disease, with improved stability over natural antibodies.

Professor Cameron Jones Room No. 1.10, Tel: 9902 0391, email: cameron.jones@monash.edu Group website: www.monash.edu/science/research-groups/chemistry/jonesgroup Modern Main Group Chemistry In the past 10 years remarkable progress has been made in the chemistry of very low oxidation state and low coordination number s- and p-block compounds. It is now possible to prepare and investigate the fascinating reactivity of compounds that were thought incapable of existence until a few years ago. The fundamental and applied aspects of this area are rapidly expanding in the Jones group (see group website for further details). Representative examples of the many potential Honours projects that are available within this exciting area are as follows: (i) Low oxidation state Main Group systems: replacements for transition metal catalysts. In recent years "trans-bent" compounds containing multiple bonds between two p-block metal(I) centres have been stabilised by ligation with extremely bulky alkyl or aryl substituents (R). These include the remarkable heavier group 14 analogues of alkynes, viz. REER (E = Si, Ge, Sn or Pb). In this project you will prepare examples of related bulky amido substituted "metalynes" (see picture), and related compounds, and explore their use for the reversible reductive activation of H2, CO2, NH3, ethylene etc. If this can be achieved, the exciting possibility exists to use such compounds as replacements for expensive and toxic transition metal catalysts in numerous industrial processes; and for the conversion of the Greenhouse gas, CO2, to useful chemical products such as methanol. see: (i) J. Am. Chem. Soc., 2014, 136, 5283; (ii) J. Am. Chem. Soc., 2012, 134, 6500; (iii) J. Am. Chem. Soc., 2011, 133, 10074; (iv) Nature, 2010, 463, 171. (ii) Stabilisation and application of complexes of Group 2 metals in the +1 oxidation state. It has previously been only possible to prepare compounds containing the Group 2 metals (Be, Mg or Ca) with the metal in the +2 oxidation state. Recently, we have reversed this situation with the landmark preparation of the first thermally stable compounds to contain Mg-Mg bonds (e.g. see picture). The formal oxidation state of the magnesium centres in these compounds is, therefore, +1. As a result, these species are highly reducing, a situation which has lent them to use, in our laboratory, as specialist reagents in organic and organometallic synthetic methodologies. You will further explore this potential, in addition to examining the possibility of preparing the first dimeric calcium(I) compounds. Furthermore, you will examine the use of such systems as soluble models to study the reversible addition of dihydrogen to magnesium metal (yielding MgH2). This poorly understood process is of great importance for future hydrogen storage technologies which will be essential for viable zero emission vehicles powered by fuel cells. The activation of other gaseous small molecules (e.g. CO2, N2, NH3 etc.) will be investigated at high pressure (ca. 200 atm.) with the aid of high pressure sapphire NMR tube technology developed in the Ohlin group at Monash. see (i) Science, 2007, 318, 1754; (ii) J.

Dr Kamila Kochan Room No. 1.10, Tel: 9905 1407, email: kamila.kochan@monash.edu Group website: https://www.monash.edu/science/cfb Characterisation of Ru-based complexes, novel agents with promising anti-cancerous activity. From physicochemical properties to interaction with biomolecules. Recently in the medicinal chemistry metallacarboranes are gaining increasing interest, as they show promising potential biological activity. In particular, anti-proliferating activity was attributed to transition metal complex fragments. Combination of these with dicarbollide cluster leads to development of novel metallodrugs. In this work we focused on the use of [Ru(arene)]2+ groups which were identified in the last 20 years as promising alternatives to platinum-based anticancer drugs, demonstrating lower intrinsic toxicity and broad spectrum of biological activity. The novel Ru- complexes were recently designed and synthetised by a group in Leipzig University (prof. E. Hey- Hawkins). The combination of dicarbollide anion with [Ru(arene)]2+ is extremely promising not only due to potential anti-proliferative activity, but also due to highly hydrophobic properties of dicarbollide. This can enhance the transport of the metallodrugs through cell membrane and potentially has high robustness in biological condition, as it is not metabolised by any enzymes. This project focuses on characterising the properties of several novel Ru-carboranes (examples of structures of some in Fig. 1) using a computational and experimental approach (IR, Raman, UV-VIS spectroscopy). In particular, we would like to characterise aspects such as aggregation, dissociation and diffusion mechanisms of selected ruthenium complexes and examine their interaction with a series of biomolecules.

Professor Tanja Junkers Room Nr. 220A, Building 23, Tel: 03 9905 4524, email: tanja.junkers@monash.edu Group website: www.polymatter.net The Polymer Reaction Design group strives for the development of new materials via state of the art polymer synthesis methods. From fundamentals and kinetics of polymerizations to the design of new polymer reaction pathways, all elemental steps are addressed and custom-made materials are constructed. Research spans widely from synthetic chemistry projects over process design to physical properties of materials. Core research areas of the PRD group are the synthesis of sequence-defined and sequence-controlled polymers and oligomers. Such polymers bridge the gap between classical synthetic polymers and biological polymers such as peptides or RNA. Further, the group focuses on the use of continuous flow chemistry approaches for the synthesis of complex polymers and for formulation of polymer (nano)particles. Flow chemistry is an interesting tool that allows us to not only design polymers with unprecedented accuracy, but also in a simple, and automated fashion. Last, but not least, we are also working on biopolymers, either biodegradable polymers or materials made from biofeedstocks. 1. Sequence-defined oligomers for biomedical application Using the well-known RAFT polymerization strategy we design discrete oligomers that mimic peptide chains. In order to achieve this, amino-acid analogue monomers are first synthesized, followed by oligomerization and product isolation. Oligomers with encoded information will be obtained and evaluated for their biological function (antimicrobial, cell guiding). This project is very synthesis oriented and suitable for more than one student. 2. Automated flow synthesis of polymer material libraries In the PRD group we have established techniques that allows for synthesis of polymer material libraries via a self-optimizing autonomous flow reactor. Reactions are fully computer controlled and on the basis of online-monitoring data, smart algorithms take over the synthesis process and self-optimize for desired products. We want to extent this system by adding a benchtop NMR spectrometer into the system. This project is very focused on flow chemistry and process design. Knowledge in computer programming (Python, LabView) is very beneficial to carry out this project, yet not strictly required. 3. Facing dispersity: How to make discrete polymers and study of their properties Today, we are able to access a very broad variety of polymer materials, and we come very close to structure found in nature. Yet, we are still much limited when it comes to dispersity. Via advanced synthesis and advanced polymer separation we are able to bring polymers towards monodispersity. This allows us to study these materials from angles that were until today not possible. We will produce close-to-monodisperse polymers and then study their properties. The project is suited for students with synthetic interests that also want to work on the physical chemistry side of things. 4. Morphology control in continuous flow micelle formation Block copolymer micelles are ideal vehicles for targeted drug delivery, but suffer greatly from reproducibility issues and limited control over the size and shape of the micelles. Flow processes make the micelle formation more reproducible and scalable. At the same time, flow can be used to beat thermodynamics and to create micelle morphologies that are otherwise unachievable. We have very promising results for these procedures and want to investigate the possibilities of flow micelle formation much deeper. The project will involve synthesis of block copolymers, flow micellation and characterization of the resulting nanoparticles. This project is cosupervised by Rico Tabor and is suitable to students who like macromolecular synthesis as much as physical chemistry of nanoparticles. 17

If you have any further queries, please do not hesitate to contact me (details above). Chemistry education (with Assoc. Prof. Chris Thompson) Impact of personalising student feedback through Learning Analytics We are interested in using Learning Analytics to optimise student learning. Learning Analytics measure and process student data collected from Moodle (the University Learning Management System). These data allow us to personalise feedback to students, which is particularly difficult in large student cohorts. We are evaluating how student’s respond to personalised feedback, to inform us how we can better support students throughout their degree programme. Green chemistry through context-based learning We aim to prepare undergraduate students to tackle global challenges confronting modern society. To achieve this, we are designing and implementing context-based learning activities to encourage students to make links between chemistry, the environment and society. Our goal is to for students to learn about fundamental chemistry concepts and relate the concepts to their everyday life, in particular changing their actions that impact the environment. Green chemistry synthesis (with University of Groningen, Netherlands) Green chemistry catalysis We are developing site-selective catalytic methods to transform simple sugars. These reactions use photoredox catalysts and visible light to promote carbon-carbon bond formation. The reaction mechanism is proposed to occur through the coupling of two different radical reactions. We are investigating the reaction mechanism, and how various radical species and metal intermediates interact. This is important to inform design of new, site-selective synthetic reactions of more complex sugars. R (1.5 equiv) OH OH Ir cat.

With this insight, we are designing new selective radical reactions and iron-based radical mediators. 18

More information from David or http://users.monash.edu.au/~dwlupton/index.html Project A: Enantioselective catalysis with NHC- catalysis Organocatalysis has emerged as a powerful approach to reaction discovery. In 2020 attention is centered on three reactive intermediates (enediamine A, and enetriamine B, and dienyl acyl azolium C) accessible using NHC catalysts.1 Specifically their capacity to enable novel enantioselective transformations will be examined. A number of honours projects broadly based on this topic are available. Key references: 1) Nguyen X. B; Nakano Y.; Duggan, N. M.; Scott, L.; Breugst, M.; Lupton, D. W. Angew. Chem. Int.

Project B: Hybrid Biocatalysis Recently we commenced studies in collaboration with Professor Jackson (ANU) on the discovery of chemical reactions using a new type of biocatalysis in which both the protein and the cofactors (THDP) are modified to allow optimal performance. In this project we will prepare a series of new co-factors (THDP) and examine their use firstly as organic catalysts and then with wild type enzymes, which will then be modified using directed evolution approaches2 to give new hybrid biocatalysts.3 A flow chart describing this project is shown below, with section 1 and 2 conducted at Monash; 3 in collaboration.
