Metal cluster-diamondoid hybrid systems are expected to give new opportunities for studying electronic coupling mechanisms in tailor made nano scale semi-conductor systems. Diamondoids on one hand show shape and size dependent optical properties. Together with metal clusters which are mass selectable down to a size regime where every atom counts, they yield a broad range of parameters with which the electronic structure of the resulting hybrid system can be modified. First theoretical investigations hint at resonance effects for the optical and UV absorption region.
In this proof-of-principle study, we synthesized metal cluster-diamondoid hybrid systems and identified influences on the reactivity of metal clusters with (functionalized) diamondoids. Initial results, details of the experimental set-up and future extensions will be presented.
