Design and Synthesis of Molecular Reactors for the Preparation of Topologically Trapped Gold Cluster

Functionalized core/shell organosilicon micronetworks with siliconhydride groups bound to the core are utilized as active molecular reactors for colloid formation. The Figure shows the various kinetic processes (diffusion in and out, reduction, and nucleation) controlling gold colloid formation. Since reduction is strictly located in the core of the microgels the formation of topologically trapped gold clusters can be observed.
