The systematic development of fundamentally important group 15 compounds: their applications to innovative industrial and environmental processes. The strong coordinating ability of organo-phosphorus/arsonic acids will be harnessed to support a series of metallic clusters that will be exploited for their use as magnetic materials in gas storage and as catalysts. The novel acids will be investigated for use as water soluble purification agents for, for example, mercury, uranium and lead.

Metallosupramolecular Cages for Enantioselective Applications. The project aims to explore new synthetic routes to functional supramolecular cages/containers which are able to selectively host small molecules in their interior space, and may provide feedback upon the presence of a guest (i.e. molecular sensing) or catalyse reactions within the enclosed cavity. The project expects to produce chiral cages that are capable of detecting specific enantiomers in solution and act upon them.

The project aims to explore new synthetic routes to functional supramolecular cages/containers which are able to selectively host small molecules in their interior space, and may provide feedback upon the presence of a guest (i.e. molecular sensing) or catalyse reactions within the enclosed cavity. The project expects to produce chiral cages that are capable of detecting specific enantiomers in solution and act upon them. The expected outcome is a deeper understanding of the structure/property relationship of these novel species and steps towards application. This should provide benefits given the application of solution-based methods for enantioselective sensing/catalysis are of significance in high-value pharmaceutical synthesis.Read moreRead less

This project will focus on fundamental chemistry that underpins innovations in the synthesis of metal-based imaging and therapeutic agents. Radioactive isotopes of copper and zirconium can be used for either non-invasive diagnostic imaging or treatment of disease. However, it is essential that the diagnostic or therapeutic agent selectively localises in diseased tissue. This project aims to achieve the required selectivity by employing enzymatic site-specific bioconjugation reactions to build new imaging agents that feature ligands designed to safely bind radioactive isotopes fused to antibody derived targeting molecules.Read moreRead less
Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism.

Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecules and materials having memory retention, magnetic ordering and/or microporosity. The significance of these aims covers several fundamental questions in the science of electronic systems. We also identify a number of potential nanochemical switching applications for the unique systems proposed.Read moreRead less
