  RAFT Polymerization of S-Vinyl Sulfide Derivatives and Synthesis of Block Copolymers Having Two Distinct Optoelectronic Functionalities

  摘要：

  Well-defined sulfur-containing polymers and block copolymers were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of S-vinyl sulfide derivatives, in which the thioether moiety is directly connected to the vinyl group. We initially investigated RAFT polymerization of four different S-vinyl sulfide derivatives, phenyl vinyl sulfide (PVS), 4-chlorophenyl vinyl sulfide (CPVS), 2,4-dichlorophenyl vinyl sulfide (DCPVS), and 4-bromophenyl vinyl sulfide (BPVS). Three xanthate-type chain transfer agents (CTAs), a dithiocarbamate-type CTA, and a dithioester-type CTA were compared for these RAFT polymerizations. Reasonable control of the polymerization of PVS was confirmed by an observed linear increase in the molecular weight with the conversion, feasibility to control molecular weight based on the ratio of monomer consumed to the amount of CTA used, chain end structure determined by H-1 NMR, and chain extension experiment. The RAFT polymerization of the bromo-substituted monomer (BPVS) also proceeded in the controlled fashion under the same conditions. Incorporation of optoelectronic groups, including anthracene, fluorene, diphenylamine, and phenothiazine on the bromophenyl pendant group of poly(BPVS) were accomplished by palladium-catalyzed postmodifications. We also investigated characteristic optoelectronic properties of modified polymers and block copolymers with two distinct electronic functionalities.
