The polymerization of diynes （la-lc）, dialdehydes （2a and 2b） and dibenzylamine catalyzed by InC13 was carried out smoothly within 1 h under microwave radiation, yielding four soluble polymers with high molecular weights. The resulting polymers P1 and P2 could be easily dissolved in alcohol and thus utilized as the cathode interlayer for polymer solar cells （PSCs）. Compared with the control device, the PSCs with P1 and P2 as the cathode interlayer and PTB7-Th：PC71BM as the photoactive layer exhibited significantly higher power conversion efficiencies （PCEs） of 9.49% and 9.16%, respectively. These results suggest that this polycoupling reaction is an efficient approach to construct three-component polymers for the practical applications.展开更多
