摘要：

In situ conductivity of polythiophene (PT) deposits from anodic coupling of thiophene (T), bithiophene (BT) and terthiophene (TT) increases with redox switching to an extent which depends on the monomer. Changes are considerable with TT, minor with BT and negligible with T, involving extra oxidative charges with the same trend, and are paralleled by evolution of electronic and infrared spectra and cyclic voltammograms. Results are explained by the occurrence of solid-state polymerization of oligomers leading ultimately to the same polymer with a conductivity of 1-3 S cm-1. PT from thiophene is much less conducting (0.06 S cm-1), because of oxidative degradation during deposition.
