尽管这些聚合物缺乏形成有序超分子聚集体的内在趋势，但可以获得区域不规则聚（3-烷基噻吩）在膜中的有利排列。如本文所报道的，在膜形成之前，可以简单地通过氧化溶液中的聚合物来实现对准。观察到有序度和溶液中氧化水平之间的微妙平衡。这些结果指出了一种提高电荷传输效率的方法，该方法受到聚合物中链内和链间顺序的影响。
Favorable alignment of regio-irregular poly(3-alkylthiophene)s in a film can be attained, despite the fact that these polymers lack an intrinsic tendency to form well-ordered supramolecular aggregates. As reported here, alignment can be achieved simply by oxidizing the polymer in solution prior to film formation. A delicate balance between the degree of order and the level of oxidation in solution is observed. These results point to a way to improve charge transport efficiency, which is influenced by intra- and interchain order in the polymer.
