Research Interests

  • Precise synthesis of Ligand-protected Subnanometer Metal Clusters

  • Interface of Iinorganic Nanoentities and Organic-based Molecules.

  • Supramolecular Aassembly of Clusters ("Cluster of Clusters")

  • Supramolecular/Macromolecular Chemistry of Multimetallic Compounds

Design of inorganic nanoclusters with defined organic spaces for the creation of unique functions for Environmental Science

  • The aim of this research is to merge inorganic cluster chemistry and organic-based chemistry (e.g., coordination, supramolecular, macromolecular, host-guest...) at the molecular level for the development novel functional materials/molecules that may contribute environmental sciences. Our basic approach is to construct tailor-made proximal spaces made of organic-based compounds to create unique functions and pursue unusual phenomena arising from the molecular events at the interface of the two different species.
  • Examples include precise synthesis of ultrasmall gold clusters and surface-functionalized semiconductor (CdS, CdSe..) clusters for photoluminescence sensing, gold cluster / porphyrin hybrid systems for catalyses, and porous crystalline materials composed of polyoxometalate and organic compounds for selective accommodation of small molecules.
