(Terthiophene)4–poly(amidoamine)–C60 pentad 8a and (terthiophene)2–poly(amidoamine)–C60 triad 8b have been synthesized with the aim of developing novel precursors for photoinduced polymerization. The electrochemical oxidation of pentad 8a by repetitive cyclic voltammogram scans gave a polymeric 8a film on a FTO electrode, which showed electrochemical activity and photoelectric response. When a monomer film of 8 on FTO was irradiated with visible light, the photoinduced polymerization of the terthiophene moiety was observed. The photoanodic features of an electropolymerized film of 8a on a FTO (poly-8aelectro/FTO) and 8a/FTO were investigated regarding photocurrent response to light irradiation. The photocurrent of a photopolymerized 8a film on a FTO (poly-8aphoto/FTO) electrode formed by photoreaction of 8a/FTO, is approximately 6 times greater than that of the 8a/FTO electrode.
合成了(三联噻吩)4-聚(酰氨基胺)-C60五联体8a和(三联噻吩)2-聚(酰氨基胺)-C60三联体8b,目的是开发用于光诱导聚合的新型前体。通过重复循环伏安扫描对五联体 8a 进行电化学氧化,在 FTO 电极上生成聚合物 8a 薄膜,该薄膜表现出电化学活性和光电响应。当用可见光照射FTO上的8的单体膜时,观察到三联噻吩部分的光诱导聚合。研究了 FTO(聚 8a 电/FTO)和 8a/FTO 上 8a 电聚合膜的光阳极特性,研究了其对光照射的光电流响应。通过8a/FTO的光反应形成的FTO(poly-8aphoto/FTO)电极上的光聚合8a膜的光电流大约是8a/FTO电极的6倍。
