Organometallic Switches in Nonlinear Optics

The drive to miniaturize has focused attention on switching properties of molecules using external stimuli. Thus far, this focus has been largely directed at linear optical read-out. Nonlinear optical (NLO) read-out may be advantageous: reversibly-switchable NLO properties expand the range of light sources to the infrared and telecommunications realm, and offer enhanced spatial control due to the higher-order light-intensity dependence. This project will target dipolar, quadrupolar, and cluster-based organometallics as reversibly-switchable NLO materials. These complexes may be of interest in the nascent field of molecular logic, and the project will cement Australia's position as a leader in NLO properties of organometallics.
