Studies of Group 15 complexes of the Lanthanoids and Group 2 metals-An unexploited field of research. The project will initially explore new amido chemisty of the lanthanoids. This chemistry will develop towards complexes with lanthanoid-or Group 2-phosphorus, -arsenic, -antimony or -bismuth connectivities. This chemistry is surprisingly underdeveloped given the wealth of applications found for oxo and amido complexes of the same metals.

The project will initially explore new amido chemisty of the lanthanoids. This chemistry will develop towards complexes with lanthanoid-or Group 2-phosphorus, -arsenic, -antimony or -bismuth connectivities. This chemistry is surprisingly underdeveloped given the wealth of applications found for oxo and amido complexes of the same metals. Structural studies involving the complexes using cutting edge ligands will reveal interesting coordination modes. The discovery of new reaction pathways will be of interest to the wider chemical community. The chemical reactivity and potential catalytic or luminescent properties of these compounds will be studied and will result in publications in international journals.Read moreRead less

Future advances in data storage technology and other areas of electronics depend on the miniaturisation of the relevant components. The goal of this project is to create materials where individual molecules can be the units of magnetic memory for high density data storage or the switches in electronic devices. Fundamental research in these areas is being pursued vigourously overseas and Australian involvement through this project is important for the possibility of local development of devices based on the new materials.

The development of advanced materials and frontier technologies such as the luminescent chelates proposed here is essential for Australia's evolution as a competitive nation in fields such as biomedical imaging and clinical diagnostics. For example, the total expenditure on fluorescent reagents in 2004 exceeded US$1.5 billion, with an estimated 25% annual growth. With proven applications in diagnostic immunoassay and high throughput screening, the use of luminescent lanthanide complexes allows significant improvements over traditional fluorophores, facilitating miniaturisation and ultimately leading to reduced costs for the consumer.Read moreRead less

Development and Testing of Novel Contrast Agents for Diagnostic Imaging. Demand for diagnostic imaging in the Australian healthcare system is growing at over 5% per annum. To facilitate imaging, Australia imports radiographic contrast media costing in excess of $50 million every year. Existing iodine-based agents are not ideal for X-ray absorption in current CT scanners and also cause moderate to severe allergic reaction in around 5% of all patients, sometimes with fatal results. New radiograph ....Development and Testing of Novel Contrast Agents for Diagnostic Imaging. Demand for diagnostic imaging in the Australian healthcare system is growing at over 5% per annum. To facilitate imaging, Australia imports radiographic contrast media costing in excess of $50 million every year. Existing iodine-based agents are not ideal for X-ray absorption in current CT scanners and also cause moderate to severe allergic reaction in around 5% of all patients, sometimes with fatal results. New radiographic media, which give enhanced contrast and provide greater patient comfort and safety are essential. Even a small fraction of the international market would generate millions of dollars in income, support growth and expertise in Imaging Technologies, and provide new markets for Australian mining of rare earth and bismuth metals.Read moreRead less

This project will make a landmark contribution to two areas of metallohydride chemistry. Both studies will utilise and develop metals that have traditionally been mined and exported from these shores while concurrently imported as value added products at vastly inflated cost. This research will identify knock-on applications in order to stem this financial bias. The new paths to rare earth (= Ln) hydrides will have broad industrial appeal, particularly for new materials, where, like similar group 13 materials, they may be used in the deposition of Ln films or even as precursors to superconducting solids. It is anticipated industrial collaboration will ensue. Australia will be promoted as a developer and innovator of frontier technologies.Read moreRead less
