摘要：

Four novel random poly(3-hexylthiophene) copolymers containing 5-20% of 3-cyanothiophene are synthesized by Stille polycondensation; and their electrochemical, optical, charge transport, and photovoltaic properties are investigated. All polymers show high efficiencies and high open-circuit voltages (Voc) up to 0.81 V with a PC61BM acceptor in organic solar cells. Copyright © 2014 Wiley Periodicals, Inc.
