Future Plan
Our laboratory will develop practically useful organic semiconductors and related applications including organic transistors, organic electroluminescence, and organic photovoltaic devices in the near future.

Messages to Students
I hope you will join us in our mission to produce conceptually new organic semiconducting materials by using organic synthetic chemistry.
