一种新型吡咯并吡咯二酮衍生物的设计与合成

Design and Synthesis of A Novel Derivative of pyrrolo[3,4-c]- pyrrole-1,4(2H, 5H)-dione

摘要:

以2,2'-联二噻吩为原料，通过溴化、选择性还原、氨基化环化、甲酰基化、加成-消除反应及缩合反应等成功合成了一种新型的吡咯并吡咯二酮衍生物(I)，并通过核磁共振谱、傅里叶红外光谱、质谱和元素分析等对其结构进行表征。该化合物具有良好的溶解性能，其溶液呈现鲜艳的紫红色，在可见光区530-700 nm范围有强吸收，可望成为低能隙聚合物太阳能电池材料的重要结构单元，从而获得转化率高的光伏器件。

Abstract:

A new 1,4-diketopyrrolo[3,4-c]pyrrole(DPP)-based molecule (I) was designed and successfully synthesized with 2,2'-bithiophene as starting material via bromination, selective debromination, amination, alkylation, cyanation，condensation etc., and the product and precursors were confirmed by 1H NMR, 13C NMR, IR, MS and elemental analysis.Compound (I) shows good solubility in organic solvents, and an intense absorption between 530-700 nm.
