Research Theme 1

Polymer Synthesis from myo-Inositol

myo-Inositol is a naturally occurring cyclic hexaol that is contained in rice bran. Our research focus is derivation of myo-inositol into various monomers with rigid skeletons that would useful for synthesizing high performance polymers. We have demonstrated several syntheses of polymers with rigid fused ring systems in the main chains and revealed their high heat resistance. "Accessing High Performance Polymers Using Natural Compounds as Starting Materials" is our target.

Research Theme 2

Development of C-C Bond Forming Reactions Driven by Visible Light

A new photo-induced coupling reaction of aldehydes and imines has been developed using perylene, a polycyclic aromatic compound that can be excited by visible light. As a light source, a commercially available white LED can be used. The reaction requires no heating and is metal-free. Its application to sunlight-driven reactions is anticipated.
