摘要

Sulfur-containing polymer sand block copolymers with the ability to self-assemble represent one of the most exciting functional materials, since hierarchical structures derived from the self-assembly affect the optoelectronic properties of the products and can lead top otential applications in advanced optoelectronic fabrications. Recent progress of reversible addition-fragmentation chain transfer(RAFT)polymerization allowed for the synthesis of well-defined polymers with complex architectures. Here, we present our recent study on the controlled synthesis of optoelectronic polymers and nanomaterials by RAFT polymerization of sulfur-containing monomers. Core-shell hybrids having polythiophene core were synthesized using self-assembled block copolymers having cross-linkable precursor, followed by Suzuki coupling reaction. 1)RAFT polymerization of a doubly polymerizable monomer, vinythiophene derivative, was employed for thesynthesis of the cross-linkable polythiophene precursor. Cross-linked block copolymer micelles based on the covalent stabilization and tailoring of self-assembled nanostructures have provided a versatile means to afford robust functional nanoparticles. Sulfur-containing polymers and block copolymers having characteristic optoelectronic properties were also prepared by RAFT polymerization of S-vinyl sulfide derivatives. 2)RAFT polymerization of the bromo-substituted monomer proceeded in the controlled fashion. Incorporation of optoelectronic groupson the bromophenyl pendant group were accomplished by palladium-catalyzed post modifications. Various block copolymers with two distinct electronic functionalities were obtained by the method, which showed characteristic assembled structures and optoelectronic properties. We will also present the synthesis of thermoresponsive core-shell nanoparticles with cross-linked optoelectronic cores. This work has been supported by a Grant-in-Aid for Scientific Research from the Ministry of Education, Culture, Sports, Science, and Technology, Japan(24350053).
