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. 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 molecul ....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. 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

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
Nanomagnetic Molecular Materials. This research project involves the preparation of new molecular magnets using metals such as manganese and vanadium and a study of their physical properties. Metal compounds of the cluster type are significant since they are nanoscale in size and offer new quantum features, with an improved understanding of the magnetic properties as a primary outcome and long term possible use in future quantum computers.

Nanomagnetic Materials from Molecular Clusters and Coordination Polymers. Magnetic materials are important through their use in recording tapes and other electronic devices. Traditional magnetic materials are metals, alloys or metal oxides made by high temperature methods. Our aims are to synthesize new chemical and molecule based solid materials which possess the properties of traditional magnets but which are made by careful chemical design at ambient temperatures. We will make materials which ....Nanomagnetic Materials from Molecular Clusters and Coordination Polymers. Magnetic materials are important through their use in recording tapes and other electronic devices. Traditional magnetic materials are metals, alloys or metal oxides made by high temperature methods. Our aims are to synthesize new chemical and molecule based solid materials which possess the properties of traditional magnets but which are made by careful chemical design at ambient temperatures. We will make materials which have three-dimensional network structures or large clusters of ions such as manganese bridged by organic molecules. Their magnetic properties will be studied in detail. The cluster compounds are significant since they are nanoscale in size and offer new features, with long term possible use in future quantum computers.Read moreRead less
