Abstract
Developing a fully conjugated block copolymer with a specific molecular weight and block ratio is crucial for understanding the impact of the bulk heterojunction morphology on device performance in organic photovoltaic devices. Herein, we have revealed a strategy to synthesize fully conjugated amphiphilic diblock copolymers in one pot by combining Suzuki and Stille pseudoliving polymerizations. Our strategy was to synthesize asymmetrically functionalized push-pull monomers as precursors for the synthesis of the donor polymer poly[4,8-bis(5-(2-ethylhexyl)-4-hexylthiophene-2-yl)-benzo[1,2-b:4,5b′]dithiophenebenzo [c][1,2,5]thiadiazole] p(BDT-BT) and the acceptor polymer poly[N,N′-bis(2-octyldo..
