Metal-Chelate Dye-Controlled Organization of Cd_(32)S_(14)(SPh)_(40)~(4-) Nanoclusters into Three-Dimensional Molecular and Covalent Open Architecture

摘要

Because of their interesting and unique structures and properties,chalcogenide tetrahedral clusters have attracted increasing attention.Geometrically,chalcogenide tetrahedral clusters generally fall into one of three series:supertetrahedral clusters (Tn),pentasupertetra-hedral clusters (Pn),and capped tetrahedral clusters (Cn).In addition to the synthesis of clusters with novel compositions and structures,there has been a strong desire to organize these clusters into open-framework architecture that may have use as nanoporous semiconductors.Compared to porous oxides,these chalco-genides are characterized by the integration of open architecture with semiconductivity and might find applications beyond those of traditional insulating oxides.Such applications include photocatalysis,photovoltaics,and sensing.
