The project aims to develop industrially scalable and environmentally friendly methods for synthesis of sequence-defined multiblock copolymers (polymer chains containing segments of different polymer types) using automated synthesis methods. The materials to be explored will be largely based on renewable biomass-derived monomeric building blocks. Such polymers are able to undergo microphase separation into spatially periodic compositional patterns, thereby providing access to a vast range of nano-engineered materials. This would enable design and synthesis of new advanced materials, making use of renewable resources and supporting the circular economy, with diverse potential applications ranging from nanomedicine to materials science.Read moreRead less

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
Smart materials for atmospheric water management and water harvesting. Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive. We propose novel hyper-absorbent desiccating polymers combined into sorption-powered engin ....Smart materials for atmospheric water management and water harvesting. Fresh water is a scarce resource in many parts of the globe but uncomfortably over-supplied in other regions. Dehumidifying machines, such as air conditioners, are extensively used in humid climates to enhance human comfort, but with great energy costs. Likewise, the production of potable water in remote dry regions is energy intensive. We propose novel hyper-absorbent desiccating polymers combined into sorption-powered engines inspired by nastic movements in plants to develop extremely efficient dehumidifiers and water harvesting machines. These polymer actuators can help address the auto-acceleration of climate change caused by the increasing use of air conditioners and provide cheap, clean water for remote communities.Read moreRead less

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

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
Boron Nitrogen Isostere-Doped Organometallics for Molecular Electronics. The challenge of connecting two or more metals by a single chain of carbon atoms attracts intense study, thereby mimicking electronic circuitry at the molecular level. BN-Isosteric compounds involve selectively replacing (doping) carbon atoms with the elements boron (B) and nitrogen (N). These unprecedented materials should emulate and likely exceed the properties of all-carbon systems. This project aims to design and s .... Boron Nitrogen Isostere-Doped Organometallics for Molecular Electronics. The challenge of connecting two or more metals by a single chain of carbon atoms attracts intense study, thereby mimicking electronic circuitry at the molecular level. BN-Isosteric compounds involve selectively replacing (doping) carbon atoms with the elements boron (B) and nitrogen (N). These unprecedented materials should emulate and likely exceed the properties of all-carbon systems. This project aims to design and synthesise the first molecular BN-isosteric carbon-wire materials including examples based on metal-carbon multiple bonding. Expected outcomes beyond their isolation include high-level interrogation of the structure-function behaviour of their electrical and optical properties relevant to the technologies that will emerge.Read moreRead less
