摘要：

A series of medium bandgap polymers based on 9,10-thienylanthracene and benzothiadiazole are synthesized. The optical, electrochemical, intermolecular, and charge transport characteristics of the polymers are tuned by the introduction of various substituents. The fluorine-substituted polymer exhibits much enhanced charge generation with reduced bimolecular recombination, thereby achieving a high power conversion efficiency exceeding 8%. © 2015 WILEY-VCH Verlag GmbH & Co.
