Thiophene-based D-A-D π-conjugated systems containing triphenylamine end groups connected to a 1,1,4,4-tetracyanobuta-1,3-diene acceptor by oligothiophene chains of variable length have been synthesized. These compounds show interesting light-harvesting properties and low-lying HOMO levels. Preliminary results on bilayer heterojunction solar cells with C(60) as acceptor show power conversion efficiency higher than 1.0%.
基于噻吩的 D-A-D π 共轭体系,其末端基团为三苯胺,通过不同长度的寡聚噻吩链与 1,1,4,4-四氰基丁二烯受体相连。这些化合物表现出有趣的光收集性能和较低的 HOMO 能级。以 C(60)为受体的双层异质结太阳能电池的初步结果表明,其功率转换效率高于 1.0%。
