New high performance materials are required for applications in photonics, an area of increasing importance for Australia's high technology industries. This project addresses two critically important requirements in photonics: materials with enhanced nonlinear optical merit (both quadratic and cubic), needed for applications in optical communications, data storage and computer systems, and materials with significant optical limiting properties, required for laboratory optical device protection and military applications. Concomitant with these studies, the fundamental organometallic chemistry of alkynylmetal complexes and clusters will be developed, leading into oligomeric, dendritic and polymeric species which are of intrinsic, as well as applied, interest.Read moreRead less

Transition metal clusters are closed polyhedral molecules that have been studied intensively for many years, initially for intrinsic interest, and subsequently as models of / precursors for catalysts effecting industrially important chemical transformations. More recently, clusters have been identified as promising optical limiters, required for many technological applications including optical device and eye protection from high power lasers. By focussing on the syntheses, electronic and optical properties of specific monomeric, oligomeric (including macrocyclic), dendritic and polymeric cluster-containing systems, we will develop fundamental cluster chemistry, prepare processable functional polymetallic materials, and probe the possible utility of cluster-based materials as optical limiters.Read moreRead less

Free radical generation and reactions in ultrasound assisted processes. The project is designed to give a full quantitative physical and chemical account of the free radicals generated from the passage of ultrasound through a liquid. The study will be end-focused to produce advanced materials of potential use as catalysts in fuel cells and other materials that may be used in diagnostic and therapeutic applications.
Investigation and Prediction of the Novel Properties of Dendrimers. Dendrimers are a new class of highly branched polymers, which have, until now, been difficult to characterise by conventional means. This project will develop and apply molecular simulation techniques to reveal the chemical and physical properties of dendrimers and their interactions with other molecules. These novel molecules potentially have beneficial applications to areas such as drug delivery and electronic materials. Th ....Investigation and Prediction of the Novel Properties of Dendrimers.

All-carbon molecules in metal complexes - novel materials and intermediates. An important requirement for the future is new materials with unusual properties that can be controlled.

An important requirement for the future is new materials with unusual properties that can be controlled. The need for ever smaller electronic devices requires knowledge about appropriate properties (particularly electronic) of molecules designed to model devices such as wires, switches, etc. This work seeks to design, measure and evaluate such molecules, which are based on chains of carbon atoms linking metal centres which can gain or lose electrons readily. As the electronic structure changes, so do the physical (photo, solid-state) and chemical properties (reactivity). Improved understanding of these features will benefit development of advanced technology and new materials.Read moreRead less
