Synthetic and theoretical studies of metal complexes containing carbon-rich ligands. Previous studies in my group, in conjunction with synthetic and theoretical chemistry groups at the Université de Rennes 1, France, have delineated the properties of a series of complexes containing carbon chains linking two metal centres. Having achieved a partial understanding of the features which result in good electronic communication between the metal centres via the carbon chain, the present proposal see ....Synthetic and theoretical studies of metal complexes containing carbon-rich ligands. Previous studies in my group, in conjunction with synthetic and theoretical chemistry groups at the Université de Rennes 1, France, have delineated the properties of a series of complexes containing carbon chains linking two metal centres. Having achieved a partial understanding of the features which result in good electronic communication between the metal centres via the carbon chain, the present proposal seeks to extend this collaboration to further studies which will generate related compounds in which actual eletron exchange can occur, i.e. leading to oxidation/reduction, by using compounds in which two or more different metal centres are present. This may lead to development of nano devices, e.g. molecular-scale switches. If one of the centres is activated by light, a photo-active sensor may result.Read moreRead less
Harnessing light and electricity to drive chemical synthesis. This project will explore and establish original strategies that use inputs of energy (light and electricity) to break or form chemical bonds, which can provide new or improved access to valuable compounds. In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes ....Harnessing light and electricity to drive chemical synthesis. This project will explore and establish original strategies that use inputs of energy (light and electricity) to break or form chemical bonds, which can provide new or improved access to valuable compounds. In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes of the project will include the development of new technology for organic synthesis and forging novel approaches for chemical alkylation and cross-coupling reactions. This can contribute to making important compounds more efficiently, safely and cheaper to produce in the future.Read moreRead less
Organometallic Transformations of Organic Compounds. The program will develop new metal-based catalysts for two main purposes (i) transforming basic hydrocarbons eg. natural gas and low-molecular-weight petroleum products into more advanced compounds (such as alcohols, alkenes and carboxylic acids); and (ii) converting nitrogen gas into nitrogen-containing compounds eg. ammonia or ammonia derivatives. In both projects, the aim is to take readily available and abundant starting materials that ar ....Organometallic Transformations of Organic Compounds. The program will develop new metal-based catalysts for two main purposes (i) transforming basic hydrocarbons eg. natural gas and low-molecular-weight petroleum products into more advanced compounds (such as alcohols, alkenes and carboxylic acids); and (ii) converting nitrogen gas into nitrogen-containing compounds eg. ammonia or ammonia derivatives. In both projects, the aim is to take readily available and abundant starting materials that are currently difficult to utilise and to design and develop specific reagents to convert them to "value-added" products. The program will also explore the mode of action of metal-based reagents leading to better reagent and catalyst design.Read moreRead less
Advanced cluster materials for optical limiting applications. Materials with significant optical limiting properties are needed for optical device and personnel protection against accidental exposure and hostile threat from high-power lasers. Metal clusters (molecules with several metal atoms) are one of the most promising optical limiting materials known, but while their potential has been highlighted, the systematic studies needed to optimise their performance are lacking. This project will as ....Advanced cluster materials for optical limiting applications. Materials with significant optical limiting properties are needed for optical device and personnel protection against accidental exposure and hostile threat from high-power lasers. Metal clusters (molecules with several metal atoms) are one of the most promising optical limiting materials known, but while their potential has been highlighted, the systematic studies needed to optimise their performance are lacking. This project will assess the optical limiting merit of carefully targeted cluster complexes, and afford structure/property relationships to guide materials development. Read moreRead less

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
Charging transition metals with activating alkanes. The project aims to engineer positively charged metal complexes and use them to explore the chemistry of bound activated alkane ligands. The transformation of cheap, plentiful alkanes into more valuable products is a major quest in chemistry, and complexes of alkanes bound to metals are expected to play a key role in transformations of alkanes. The project intends to use the activated metal bound alkane to transform the normally inert alkane in ....Charging transition metals with activating alkanes.

The transformation of cheap, plentiful alkanes into more valuable products is a major quest in chemistry, and complexes of alkanes bound to metals are expected to play a key role in transformations of alkanes. The project intends to use the activated metal bound alkane to transform the normally inert alkane into compounds with desirable functional groups. This should make the synthesis of alkane complexes stable at room temperature in solution a realistic possibility. These cheap, plentiful alkanes can be turned into more valuable products, bringing benefits to industry.Read moreRead less

Utilising nature's complexity - understanding fundamental organometallic binding modes of furans and coordination of bioderived furans. The earth's decreasing reserves of fossil fuels has prompted an intense push to utilise the renewable bioresources to replace the many products and fuels derived from petroleum.

The earth's decreasing reserves of fossil fuels has prompted an intense push to utilise the renewable bioresources to replace the many products and fuels derived from petroleum. One of the promising developments is the production of so-called Furanics, useful molecules produced easily from carbohydrates found in waste materials from the sugar, corn and forestry industries. Given Australia's wealth of agricultural resources, discovering the full power of these potentially useful furanic compounds should be a major priority. This research aims to link Australia's biomass potential with the plastics, pharmaceutical, fine and agrichemical industries.Read moreRead less
