Summary
Anion-templated functional architectures. This project aims to introduce a method for preparing large, complex materials from relatively simple precursors. Negatively-charged species, anions, will be used to assemble positively-charged organic molecules into three-dimensional structures, including cages and porous framework materials. This will increase fundamental understanding of how anions behave and their use in self-assembly processes. The structures made using this approach are expected to ....Anion-templated functional architectures. This project aims to introduce a method for preparing large, complex materials from relatively simple precursors. Negatively-charged species, anions, will be used to assemble positively-charged organic molecules into three-dimensional structures, including cages and porous framework materials. This will increase fundamental understanding of how anions behave and their use in self-assembly processes. The structures made using this approach are expected to remove dangerous environmental pollutants from water and store the industrially-relevant gases, hydrogen and carbon dioxide. This offers potential applications in clean energy technology (e.g. hydrogen storage for fuel cells) and environmental remediation (carbon dioxide storage, polycyclic aromatic hydrocarbon removal).Read moreRead less
pH Switching of Radical Reactivity and Orbital Conversion. Radicals are reactive species that have an unpaired electron, which is usually located in the highest occupied orbital. This proposal uses a combination of theory and experiment to design a new class of radical anions whose unpaired electron is not the highest occupied orbital, and whose electronic configuration reverts to the normal aufbau configuration upon protonation. These special radical anions will display unprecedented radical st ....pH Switching of Radical Reactivity and Orbital Conversion. Radicals are reactive species that have an unpaired electron, which is usually located in the highest occupied orbital. This proposal uses a combination of theory and experiment to design a new class of radical anions whose unpaired electron is not the highest occupied orbital, and whose electronic configuration reverts to the normal aufbau configuration upon protonation. These special radical anions will display unprecedented radical stability that is pH switchable, as well as ferromagnetism and conductivity upon oxidation. This project will exploit these unusual properties in the design of pH-switchable protecting groups for radicals for synthesis and polymerisation, and determine their role in oxidative stress and enzyme kinetics.Read moreRead less

Signature of vibrational motions encoded into small polyatomic spectra. Using revolutionary state-of-the-art spectrometers, the project plans to search for signatures of large-amplitude vibrational motions that transform one chemical species to another. Bond-breaking chemical reactions necessarily involve highly vibrationally excited reactants and/or products that move the energy of the system away from equilibrium. It is now possible for direct measurements to be made of the changes that a mole ....Signature of vibrational motions encoded into small polyatomic spectra. Using revolutionary state-of-the-art spectrometers, the project plans to search for signatures of large-amplitude vibrational motions that transform one chemical species to another. Bond-breaking chemical reactions necessarily involve highly vibrationally excited reactants and/or products that move the energy of the system away from equilibrium. It is now possible for direct measurements to be made of the changes that a molecule undergoes as it transits across a chemical potential energy barrier. The project plans to examine the long-standing problem of vinylidene-acetylene isomerisation in order to verify the long-suspected existence of large amplitude vibrational motion in small molecules, which are thought to be the signatures of a particular class of chemical dynamics. These would provide a rational basis for future control of unimolecular chemical reactions.Read moreRead less
Exploitation of unusual patterns of reactivity of peptides towards radicals. Life depends on free radical reactions of peptides and proteins but, for these compounds to exist, these must be inherently resistant to radicals. This project aims to combine state-of-the-art experiment and theoretical computations to build a detailed picture of peptide and protein radical reactivity, in order to explain this paradox and resolve ambiguities regarding processes through which radical damage to peptides o ....Exploitation of unusual patterns of reactivity of peptides towards radicals. Life depends on free radical reactions of peptides and proteins but, for these compounds to exist, these must be inherently resistant to radicals. This project aims to combine state-of-the-art experiment and theoretical computations to build a detailed picture of peptide and protein radical reactivity, in order to explain this paradox and resolve ambiguities regarding processes through which radical damage to peptides occurs and is repaired. The project also aims to critically evaluate the basic concept of the fidelity of amino acid incorporation during protein biosynthesis. The results of this project could underpin the development of new strategies and therapeutics to treat human diseases, and new materials and synthetic methods to increase the utility of peptides in biotechnology.Read moreRead less

This project aims to build a physical-organic chemistry framework of transferable molecular descriptors for a relatively new but a rapidly developing area of unimolecular electronics (UE) using advanced computational chemistry tools. Established structure-property relationships will drive the cutting-edge applications of UE in sensing and catalysis and significantly expand our understanding of charge transport involving free radicals and non-covalent assemblies. Expected outcomes of this project include new design guidelines and candidate molecular architectures for such practical applications as organocatalysis inside molecular junctions, molecular spintronics and molecular sensors for reactive oxygen species and nitroaromatic pollutants.Read moreRead less
Understanding the Chemical Processes Involved in the Metabolism of Peptide Hormones. Peptide hormones regulate normal physiological activity in humans, and their over-production causes diseases such as cancer. The aims of this project are: to delineate the chemical processes through which these hormones are produced; to develop inhibitors of enzymes involved in hormone production, and agonists and antagonists of receptors through which the hormones act; and to study the ability of the inhibitors ....Understanding the Chemical Processes Involved in the Metabolism of Peptide Hormones. Peptide hormones regulate normal physiological activity in humans, and their over-production causes diseases such as cancer. The aims of this project are: to delineate the chemical processes through which these hormones are produced; to develop inhibitors of enzymes involved in hormone production, and agonists and antagonists of receptors through which the hormones act; and to study the ability of the inhibitors, agonists and antagonists to override and bypass the chemical control mechanisms through which hormone levels are usually maintained at homeostasis. The research is expected to lead to a better fundamental understanding of hormone metabolism, and to underpin the basis for the development of new disease therapies.Read moreRead less
