This project aims to prepare highly reactive rare earth organometallic and metal-organic compounds, especially from the free metals, and to determine their structures and reactivity. Abundant rare earth resources position Australia to be a major supplier of these strategic elements. The challenging target systems include coordination stabilised novel ligands, pseudo-Grignard reagents LnR(X) including the rare fluorides, complexes primed for carbon-fluorine activation, and intermediates from use of lanthanoid reagents in organic synthesis. The project will provide a knowledge base and expertise for the utilisation of Australia's abundant rare earths and will transform the current behaviour of the elements. It builds the expertise and knowledge needed to underpin Australian rare earth processing and develops the breakthrough science needed for new applications in fine chemical manufacturing, catalysis and recycling.Read moreRead less

Targeting Bio-Compatible Homo- and Hetero-bimetallic Cages and their Application in High Energy and Dual Energy Computed Tomography. The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved.

The project is focused on the synthesis, characterisation and stability of novel homo-metallic and hetero-metallic oxygen and sulfur based cage compounds which have the potential to be suitable for high energy and Dual Energy CT imaging (DECT), and also for optical imaging where rare-earth metals are involved. Pre-requisites for cage design are that they be stable and soluble in aqueous media, and be resistant to anionic ligand exchange at the cluster surface. The targeted metals are based on good attenuation at high (100 to 140 keV) and low X-ray (less than 30 keV) energies, and the possibility of high stability and low toxicity.Read moreRead less

National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and m ....National magnetochemical facility. New magnetic materials of the molecular or biological types are quite different to traditional metal oxide magnets widely used, for example, in recording devices. They are very important from the perspective of understanding fundamental properties at low temperatures, in high magnetic fields, or when irradiated by light, but they are also showing promise in a range of applications, such as memory devices and smart cards and in the new area of spintronics and molecular computers. The magnetochemical projects described here, that require the new equipment being sought, are fundamental in nature but will provide the underpinning of future nanomagnetic materials.Read moreRead less
Illuminating hidden processes in emissive lanthanoid complexes. This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field. This project will research these processes, using chemical synt ....Illuminating hidden processes in emissive lanthanoid complexes. This project aims to understand the antenna effect used to sensitise lanthanoid luminescence. Despite their use in modern high-tech applications, from optical fibre amplifiers (telecommunications) to luminescent probes and sensors (biological imaging), understanding is largely based on speculation or generalised 'rules-of-thumb', severely limiting progress in the field. This project will research these processes, using chemical synthesis, theory and spectroscopic techniques. This is expected to lead to new emissive lanthanoid-based compounds using 'a priori' approaches, with better performance than current gold standards and references. Intellectual property created will lead to new commercial products, and to creation of new Australian based spin-off/start-up companies.Read moreRead less

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.

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
