两个新型的基于三苯胺苯并噻二唑的菁染料(I～II)通过含有该单元的苯并[e]吲哚啉乙醛和1,1,2-三甲基-3-丁 基-5-羧基-3H-吲哚碘盐的Knoevenagel缩合反应合成, 其结构用核磁和高分辨质谱进行了表征|对两个菁染料敏化剂的光物理、电化学性能和太阳能电池的光伏性能进行了系统研究. 在AM1.5G标准光源下, 两个染料的最高入射单色光子-电子转化效率值(IPCE值)均超过57%, 其光电转换效率分别为2.59%和3.28%.

Two new triphenylamine-benzothiadiazole based cyanine sensitizers (I and II) have been synthesized via Knoevenagel condensation reaction with benzo[e]indol-2(3H)-ylidene)acetaldehyde derivatives and 5-carboxyl-3-butyl-1,1,2-trimethyl-3H-indolium iodide and characterized by 1H NMR, 13C NMR, HRMS. The absorption spectra, electrochemical and photovoltaic properties were extensively investigated. The maximum monochromatic incident photon-to-current conversion efficiency (IPCE) of I and II are over 57%, but the overall conversion ef?ciency of DSSC based on dye (I and II) are only 2.59% and 3.28% under standard global AM 1.5 solar light condition.

Key words: cyanine, benzothiadiazole, dye-sensitized solar cells, photovoltaic performance
