Theme1：Development of polymer-supported chiral catalysts for catalytic asymmetric reaction
Overview
Polymer-supported chiral organocatalysts and polymer-supported chiral organometallic catalysts have been developed for the efficient synthesis of chiral product using asymmetric reaction. Immobilization of chiral catalyst onto polymer facilitates the separation of chiral product from reaction mixture. In addition, the recovered polymeric chiral catalyst can be reused. Recently,main-chain polymer of chiral organocatalyst, novel immobilization of chiral organocatalyst onto polymer, and amphiphilic polymer-supported chiral catalyst for asymmetric reaction in water have also been developed.

Theme2：Novel functional polymer microsphere
Overview
Polymer microspheres have been applied to paints, coatings, diagnostic drugs, cosmetics, precision machines, etc. Well-defined functional polymer microspheres by precipitation polymerization have been developed. These funcitonal polymer microspheres have been used for an automation flow system and a one-pot reaction for organic synthesis.

Theme3：Precise synthesis of functional polymer with branched structure
Overview
Functional polymers and branched polymers are well known to show different physical properties from homopolymer. We aim to design the precise synthesis of novel functional polymers and branched polymers for their application as efficient nano-materials. Well-defined end-functionalized polymers, multi-functionalized polymers, block copolymers, graft copolymers, star-branced polymers, and dendrimers have been synthesized with use of living polymerization technique. Well-defined polymers enables us to investigate the effect of molecular weight, molecular weight distribution, position and number of funcitonal groups, and kinds and composition of polymer on their functionality.
