摘要: Halogenation is an effective way to tune the energy levels of organic semiconducting materials. To date, fluorination materials fabricate polymer solar cells (PSCs) has been used far more than chlorination; however, fluorine exchange reactions suffer from low yields and resulting fluorinated always comes with a higher price, which will greatly hinder their commercial applications. Herein, we designed synthesized series chlorinated donor–acceptor (D-A) type polymers, in benzo[1,2-b:4,5-b]dithiophene benzothiadiazole units are connected by thiophene π-bridges asymmetric alkyl chain. These polymers showed deep highest occupied molecular orbital (HOMO) levels, promoted efficiency corresponding PSCs increasing device open circuit voltage. The chain on moieties gave final sufficient solubility for solution processing strong π–π stacking fi...
