Highly conjugated acrylate-functionalized polythiophenes from anodic coupling of thiophene- and bithiophene-hexyl acrylates

摘要

Anodic coupling of thiophene- (1) andcyclopentadithiophene- (2) hexyl acrylates in acetonitrile topolythiophenes is reported. The resulting polymers have beencharacterized by cyclic voltammetry, UV-vis and FTIRspectroscopy and in-situ conductivity. The produced polythiophenefilms, for which FTIR analysis show that the acrylate moiety iskept unchanged, display high conjugation lengths(#lambda#_(max))=520(1) and 600 (2) nm) and conductivities(20 (1) and 100 (2) S cm~(-1)).
