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

Domino Approaches to Polycyclic Natural Products. Organic molecules are the basis of all known life forms. The majority of our medicinal agents are organic molecules. Organic molecules are made up of atoms, connected together by bonds. Usually, these molecules are constructed by making one bond at a time. We are trying to make this laborious job quicker and more efficient by forming lots of bonds at once. Research of this kind is the basis for the development of new pharmaceuticals.

New Cascade Routes to Biologically Important Molecules. This research involves the development of short and efficient syntheses of several different classes of biologically active molecules using cascade reactions: spectacular events in which many chemical bonds are formed. Two distinct types of cascade reactions will be investigated and naturally-occurring molecules with antineoplastic, anti-immunosuppressive, antiviral and antimalarial activities will be prepared.

This research involves the development of short and efficient syntheses of several different classes of biologically active molecules using cascade reactions: spectacular events in which many chemical bonds are formed. Two distinct types of cascade reactions will be investigated and naturally-occurring molecules with antineoplastic, anti-immunosuppressive, antiviral and antimalarial activities will be prepared. These new, expedient routes allow the preparation of a wide range of structurally-related analogues; an important prerequisite for the preparation of libraries of compounds for biological evaluation. Along the way, important information about the chemical reactivity patterns of a newly-prepared, fundamental class of hydrocarbon molecules will be obtained.Read moreRead less
