Metal Directed Assembly of New Discrete and Framework Supramolecular Systems. An important aspect of this project is the development of strategies for assembling molecules and metals into larger units - leading to novel compounds and materials for which unusual and potentially useful properties can be anticipated. These may include materials that act as catalysts for chemical reactions or absorb and store gases (such as hydrogen for use as a fuel).

These may include materials that act as catalysts for chemical reactions or absorb and store gases (such as hydrogen for use as a fuel). More generally, the area is one that will underpin the 'bottom-up' approach (building tiny components from individual molecules and ions) in the rapidly expanding field of nanotechnology. Clearly, if Australia is to remain internationally competitive in such new technologies then an understanding of processes of the type outlined in this proposal will be essential.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. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativity between centres, induced by careful supramolecular design, will lead to molecule ....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 cooperativity 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

The proposed research will benefit Australia by creating a knowledge base in an internationally important area of chemistry. This will be aided by the return to Australia of an international leader in the field. Through an integrated and interdisciplinary approach, the exploitation of technologies arising from the research program will be explored. In addition to the academic community, these technologies will benefit hi-tech industries including pharmaceutical and fine chemicals concerns which will gain from the use of the proposed group 13 heterocycles in organic synthesis. Moreover, industries reliant on polymer supports in catalytic process or opto-electronic polymers will profit from the various polymers derived from phosphaalkynes.Read moreRead less
Design and synthesis of novel lanthanoid complexes for the fabrication of light emitting devices. There is a huge and still growing economy centred around the design and fabrication of low-cost Light Emitting Devices (LEDs), as demonstrated by the excess of US$1.3 billion invested in this field between 2000 and 2007. Nations focused on the production of new and more efficient materials will be at the forefront of these emerging technologies.

Nanoscale Molecular Architectures - New Metallo Cages and Capsules. The design and synthesis of novel cage and capsule-like supermolecular structures will be undertaken, including rare examples of two large cage types - one designed to incorporate two adjacent metal ions in an extended (chiral) cavity while the other utilises macrocyclic metal complexes as the 'walls' of the cage. In the latter case metal variation makes possible the alteration of the electronic environment of a guest occupying ....Nanoscale Molecular Architectures - New Metallo Cages and Capsules.

In the latter case metal variation makes possible the alteration of the electronic environment of a guest occupying the central cavity . A third (capsule-like) system is designed to 'open' and 'close' under pH control. The present studies hold promise for underpinning the future development of nano-scale molecular devices.
