Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is a ....Pro-Fluorescent Aryl Nitroxides: New Probes for Polymer Lifetime and Kinetics Research. Internal aryl rings present in novel probes developed for this project impart fluorescence which is efficiently and internally quenched by the presence of a paramagnetic nitroxide group. Scavenging of radicals by the nitroxide however "switches on" the fluorescence and this enables powerful new fluorescence-based detection levels for the technique of nitroxide free radical scavenging. Such sensitivity is applicable to polymerization kinetics studies, as well as providing new means for the determination of materials lifetimes. The development of pro-fluorescent markers as indicators for polymer degradation would be a significant outcome for materials where component failure has a major negative impact.Read moreRead less
Hydrogen Abstraction in Chemical, Biochemical and Polymerization Processes. Hydrogen-abstraction reactions are of vital importance in the chemical, biochemical and polymerization processes that occur in everyday life. The objective of the proposed research is to improve our understanding of such reactions.

Hydrogen-abstraction reactions are of vital importance in the chemical, biochemical and polymerization processes that occur in everyday life. The objective of the proposed research is to improve our understanding of such reactions. State-of-the-art quantum chemistry calculations will be used to examine a broad range of hydrogen-abstraction reactions, and to obtain accurate information about the factors that influence such reactions. Building on this work, more detailed case studies will be performed in two important areas: the hydrogen-abstraction steps in biochemical reactions mediated by coenzyme B12, and chain-transfer processes in conventional and controlled free-radical polymerization.Read moreRead less
Polymer-functionalised nanotubes: controlled formation by self-assembly. This project will develop new structures of nanotubes by combining peptide sequences and synthetic polymers. These nanostructured materials will form the basis of a wide range of technological applications, such as inorganic nanotubes, ion channels, drug carriers, and more broadly in nanotechnology and nanomedicine.
Understanding and controlling the stereochemistry of free-radical polymerisation. The stereochemistry of a molecule, which relates to the relative spatial arrangement of its atoms, can have a profound effect on its physical and chemical properties. This project will use a computer-guided experimental approach to design new methods for controlling the stereochemistry of the polymers formed in free-radical polymerisation.
Controlling polymer microstructure with structured Lewis acids. Radical polymerisation is the most commercially important polymer process, favoured by industry for its broad scope and relatively low cost and environmental impact. However, its use in the synthesis of 'smart materials' for biomedical applications, molecular electronics and high-performance engineering applications has been hampered by the lack of microstructural control. This project aims to use a complementary combination of theo ....Controlling polymer microstructure with structured Lewis acids. Radical polymerisation is the most commercially important polymer process, favoured by industry for its broad scope and relatively low cost and environmental impact. However, its use in the synthesis of 'smart materials' for biomedical applications, molecular electronics and high-performance engineering applications has been hampered by the lack of microstructural control. This project aims to use a complementary combination of theory and experiment to develop novel structured Lewis acids for controlling the stereochemistry in free-radical polymerisation, and to utilise the recently discovered propagation catalysis conferred by simple Lewis acids to minimise defect structures and thereby improve the thermal and photostability of polymers.Read moreRead less

Controlling chemical reactions via pH-switchable electrostatic catalysis. This project aims to establish a new approach to catalysis using the electrostatic effects of pH-switchable, charged functional groups.

This project aims to establish a new approach to catalysis using the electrostatic effects of pH-switchable, charged functional groups. Utilising simple homogeneous catalysts and polymer-supported enzyme-mimicking catalysts, a wide range of target reactions will be studied. The expected outcomes of the project will include a new approach to the design and optimisation of several new classes of catalyst for assembling complex molecules and materials. The project also offers a unique opportunity to train the next generation of chemists in the principles of computer-aided chemical design. The catalysts developed in this project will be able to accelerate and control the chemical reactions used in the synthesis of pharmaceuticals and materials, with significant practical benefits to industry.Read moreRead less
Functionalised biopolymers - a new class of renewable nano-engineered materials. Licella is an Australian start-up company, focusing on developing uses for the renewable resource lignocellulosic biomass; a fibrous material sourced principally from waste, such as that generated by forestry and agricultural operations.

Licella is an Australian start-up company, focusing on developing uses for the renewable resource lignocellulosic biomass; a fibrous material sourced principally from waste, such as that generated by forestry and agricultural operations. It is possible to use such waste and process it to separate the biomass components. This project proposes to modify these biomass fractions with living radical polymerisation (LPR) polymers to impart functionalities, such as antimicrobial properties, high tensile strengths and/or in-built photodegrability. New, high-performance sustainable materials like these will be the back-bone of the polymer/plastics industry of the future, replacing common plastics, sourced from non-renewable petrochemicals, with benign, sustainable plastics.Read moreRead less
