Our interests presently focus on the development of bioinspired transition metal clusters to mimic those metalloproteins which are connected to generation of recyclable energy, such as the pMMO and PSII enzymes.  Except the fundamental studies, we will further explore the potentiality of applications on the solar cell or fuel cell.

Coordination Chemistry: Implementation for the elucidation of bonding characteristics and electronic structures of paramagnetic metalloporphyrins using density functional calculation and NMR spectroscopy

Bioinorganic Chemistry: Development of the concept of symmetry switch by studying nonplanar metalloporphyrins as models to elucidate the biological consequences of macrocycle deformation on hemoproteins.

Catalysis: Development of chirometallo-porphyrins as enantioselective oxidation catalysts.
