摘要：

π dimerization in polythiophenes, leading to stabilization of the intermediate polaronic form, hasrecently been proposed as the origin of the distinctive twin process in the oxidation cycles of polythiophenes. Electrochemical measurements on polymers obtained by anodic cupling 4,4‐di‐n‐alkylcyclopentadithiophene (see Fugure) confirm this; the π dimerization operates when the spacing groups between the polymer strands are absent of the spacing group increases.
