报告摘要：Metal nanoclusters (NCs) with atomic precision are a unique family of metal nanomaterials that are readily crystalized into single crystals, representing ideal models to unravel structure-property relationship at atomic level. By tuning the number of metal atoms in the core, the composition and the protecting ligand of metal NCs, their physicochemical properties can be precisely controlled. The strong, broad light absorption ability and the long-lived excited states make metal NCs promising candidates as photosensitizer, and might replace traditional dyes. Their discrete energy levels allow them to prevent charge recombination at the semiconductor by efficiently separate the photoinduced charge carriers. Moreover, these metal NCs themselves can act as active catalysts.

个人简介：Dr. Wang has published 15 research articles as first/corresponding author (including 4 JACS, 2 Angew. Chem., 1 Nat. Commun.). He has been granted a project by the German Research Foundation (DFG) to support him as independent principal investigator. His current research interest is to develop universal strategies on the modification and optimization of existing photoactive materials by building atomically precise metal cluster/semiconductor cluster interface.
