Direct arylation polymerization enables “greener” synthesis of a high-performance semicrystalline π-conjugated polymer, poly[(2,5-bis(2-hexyldecyloxy)phenylene)-alt-(5,6-difluoro-4,7-di(thiophene-2-yl)benzo[c][1,2,5]thiadiazole) (PPDT2FBT). The resulting polymers show a hole mobility of 4.7 × 10−3 c...
