conjugated polymers based on furo[3,4-c]pyrrole-4,6-dione (FPD) and selenopheno[3,4-c]pyrrole-4,6-dione (SePD) have been synthesized and compared with their thieno[3,4-c]pyrrole-4,6-dione (TPD) analogues to investigate the effects of the heteroatom on the electrooptical properties. The copolymers were synthesized using either Stille cross-coupling or direct heteroarylation polymerization (DHAP), the
合成并比较了基于呋喃[3,4- c ]吡咯-4,6-二酮(FPD)和硒苯并[3,4- c ]吡咯-4,6-二酮(SePD)的新型推挽共轭聚合物他们的thieno [3,4- c] pyrrole-4,6-dione(TPD)类似物来研究杂原子对电光性质的影响。使用Stille交叉偶联或直接杂芳基化聚合(DHAP)合成共聚物,后一种方法产生高分子量。与TPD类似物相比,对于基于FPD的共聚物(硫被氧取代),观察到了带隙的低变色,而对于SePD(被硒取代的硫)观察到了小红移。这两类新的共轭聚合物具有电光特性,可导致有趣的体异质结塑料太阳能电池。
