Research Areas

Our research interests cover broad areas of organometallic chemistry, which include the synthesis of new complexes having novel structures, development of more efficient, more selective catalysts for olefin polymerization and organic synthesis, and exploration of new chemical transformation processes by use of organometallic compounds. Much of our work lies at the interfaces between inorganic, organic, polymer and material chemistries. Researchers in this laboratory have access to the state-of-the-art inert atmosphere workstations and other modern facilities for organometallic and related researches.

Research Subject

  1. New single-site catalysts for regio- and stereospecific olefin polymerization and copolymerization
  2. New organometallic catalysts for efficient organic synthesis
  3. Synthesis and synergistic reactivity of rare earth metal hydride clusters
  4. Development of novel organic electroluminescence (EL) materials
