The development of multifunctional coordination solids represents one of the foremost challenges in the field of advanced materials as their properties underpin the next generation of technologically useful devices. Using a highly targeted theoretical and experimental approach for crystal engineering, this project aims to generate coordination solids that integrate radicals as molecular components for charge transfer. At a fundamental level these materials will offer unprecedented insights into charge delocalisation and radical-induced switching phenomena in three-dimensional coordination space. It is expected that the outcomes of the project will spur the development of devices for applications ranging from solid state sensing to energy conversion and storage.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.

Summary
Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in ....Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in mixtures. The current proposal is aimed at introducing new technology into the Australian National Beamline Facility that will greatly improve the quality and quantity of experiments that can be performed and extend studies into dilute solutions and protein samples.Read moreRead less
