Advances in the development of nanotechnology have encouraged the creation of highly functionalized nanomaterials. Thiolate-protected gold clusters (Aun(SR)m), in addition to their nanoscale size (<2 nm), exhibit size-specific physical and chemical properties that are not observed in bulk metals; thus, they have been attracting significant attention as functional units or building block in nanotechnology. Among these, the highly stable, magic Aun(SR)m clusters have especially great potential as new nanomaterials. We are engaged in the following subjects for magic Aun(SR)m clusters: (1) establishing methods to enhance their functionality, (2) developing high-resolution separation methods, and (3) utilizing them as active sites in photocatalytic materials. Through these studies, we aim at the creation of highly functionalized metal clusters, and through their application, the creation of highly active photocatalysts. The results of our efforts to date are reported in this presentation.
