About

The aim of our research is the preparation of new types of potentially useful molecular materials. Understanding how chemical structure can control molecular properties is the key step, and this necessitates coupling chemical synthesis to a range of physical properties studies.

Research in the group involves organometallic, organic, coordination complex and polymer synthesis, spectroscopy, various electrochemical and spectroelectrochemical techniques, molecular modelling, electron microscopy and X-ray structural studies, and a wide range of nonlinear optical studies using high-power lasers.

Spatiotemporal light control by programmable molecules

This project will involve use of fs- and ns-pulsed wavelength-tuneable lasers, in some cases interfaced to electrochemistry equipment, to investigate NLO properties of new molecules/materials, and can involve modelling properties using the ANU’s supercomputer.

Syntheses and reactivity of high-nuclearity clusters

We have developed a remarkably easy route into certain high-nuclearity ruthenium carbonyl clusters (the figure shows a Ru12 cluster, the largest Ru cluster so far); this project will explore the chemistry of these unique compounds.
