(1) Applied Organic Chemistry
We develop new organic materials, in particular organic semiconductors for field-effect transistors, based on organic synthetic chemistry. In our research group, special emphasis is placed on an “all-in-one” research system from molecular design to device fabrication & evaluation through efficient organic synthesis. Among our recently developed new organic semiconductors, several “world-class” transistor materials have been discovered. |

(2)Organic Materials Chemistry
This research group deals with the development of novel functional materials based on organosilicon chemistry. Polysilane derivatives, and polymers and oligomers with an alternate arrangement of organosilicon units and π-conjugated systems are synthesized and their functionalities are studied. The development of new synthetic reactions utilizing finely designed transition metal catalysts and reactive intermediates, and their applications to the creation of new functional molecules are also emphasized. |

(3) Polymer Chemistry
Our major interest is the development of novel polymeric materials, especially via polymerization catalyzed by transition-metal complexes．For example, we have realized the living polymerization of 1-alkene and cycloalkene with novel organotitanium complexes to obtain high-performance tailor-made polyolefins for optical plastics. We also aim at the development of polymeric materials from plant resources. We also prepare novel porous carbon materials from common polymers by controlling the pore diameter with metal compound particles derived from organometallic compounds. |
