摘要：

Anodic coupling of mixed alkyl-alkoxy bithiophenes and terthiophenes to polymers has been performed in acetonitrile. The polymers have been characterized by cyclic voltammetry (CV), UV-vis, FTIR, and MALDI spectroscopies and in situ conductivity. Long-chain highly conducting polymers or sexithiophenes are produced by CV deposition depending on the substitution pattern. Unusual symmetry (nonhysteresis) of CV responses for the sexithiophene films is attributed to solvent swelling.
