Mixed metal clusters

Transition metal clusters are closed polyhedral molecules that have been studied intensively for their relevance in catalysis, surface science and chemical physics. 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. We have developed high-yielding routes into clusters incorporating very different metals and are exploring their reaction chemistry, electronic and optical properties, and their incorporation into polymer backbones. This has afforded the most metal-rich polymers thus far.
