of 5,7-dithien-2-yl-thieno[3,4-b]pyrazine (DTTP)-based donor−acceptor (D−A) copolymers (TP1-6) and three types of 5,7-dithien-2-yl-2,1,3-benzothiadiazole (DTBT)-based D−A copolymers (PF-DTBT, PC-DTBT, and PIC-DTBT). The optical properties, electrochemical behavior, and energy levels of these nine copolymers were investigated. The photovoltaic performance of the copolymers was compared and discussed
两种基于噻吩并[3,4- b ]吡嗪的单体,2,3-二甲基-5,7-二(2-溴噻吩-5-基)-噻吩并[3,4- b ]吡嗪和2,3通过改进的合成途径合成了-二苯基-5,7-二(2-溴噻吩-5-基)-噻吩并[3,4- b ]吡嗪。通过铃木交叉偶联反应,将这两种单体和4,7-二(2-溴噻吩-5-基)-2,1,3-苯并噻二唑分别与三个供体链段(芴,咔唑和吲哚并咔唑)共聚,得到六种类型的5,7-二噻吩-2-基-噻吩[3,4- b]吡嗪(DTTP)为基础的供体受体(DAA)共聚物(TP1-6)和三种5,7-二噻吩-2-基-2,1,3-苯并噻二唑(DTBT)为基础的D-A共聚物(PF-DTBT,PC-DTBT和PIC-DTBT)。研究了这九种共聚物的光学性质,电化学行为和能级。比较并讨论了共聚物的光伏性能,并考虑了它们的能级。
