摘要：
Two random electron donor-acceptor (D-A) polymers comprised of two acceptor moieties, difluor-obenzothiadiazole and isoindigo, and one donor moiety (P1 and P2) have been synthesized in good yields to study the effects of donor structures on organic thin-film transistor (OTFT) and bulk-heterojunction organic solar cell (BHJ-OSC) performance. Both polymers possess reasonably good solubility in common processing solvents for organic electronics. P1, which contains a benzodithiophene donor structure, shows poor charge transport ability in OTFTs and low solar power conversion efficiency (PCE) in BHJ-OSC devices with PC71BM acceptor. On the other hand, P2, with a dithienylthieno[3,2-b] thiophene donor moiety, exhibits distinctly higher hole field-effect mobility and significantly much better PCE under similar conditions. These results have demonstrated the decisive influence of donor moiety over the optoelectronic properties of D-A polymers. (C) 2016 Elsevier Ltd. All rights reserved.
