The nitration of 4,7-dibromo-2,1,3-benzothiadiazole was modified by using CF3SO3H and HNO3 as the nitrating agent, and the related yield was improved greatly. On the basis of this improvement, two new small band gap polymers, P1TPQ and P3TPQ, were developed. Bulk heterojunction solar cells based on P3TPQ and [6,6]-phenyl-C71-butyric acid methyl ester exhibit interesting results with a power conversion
以CF 3 SO 3 H和HNO 3为硝化剂,对4,7-二溴-2,1,3-苯并噻二唑的硝化反应进行改性,大大提高了相关收率。在此改进的基础上,开发了两种新的小带隙聚合物P1TPQ和P3TPQ。基于P3TPQ和[6,6]-苯基-C 71-丁酸甲酯的块状异质结太阳能电池显示出有趣的结果,功率转换效率为2.1%,光响应高达1.1μm。
