In the present work, organic sensitizers are synthesized and attached on TiO2 photoanodes via Ti-O-C bonds. All sensitizers, designed for this purpose are symmetrical and have two perfluorophenyl end groups, which can lead to stable non-hydrolysable bonds on the TiO2 surface. Broad absorption in the UV–Vis region and low band gap energy levels have been achieved through the alternation of carbazole- and benzothiadiazole-based units. All dyes and their corresponding photoanodes, were characterized via various complementary techniques, including Cyclic Voltammetry measurements and sensitization capacity in Dye-sensitized solar cell tests.

用全氟苯基锚定剂封端的有机染料:二氧化钛光阳极的合成,电化学性质和敏化能力评估
在目前的工作中,合成了有机增感剂,并通过Ti-OC键将其附着在TiO 2光电阳极上。为此目的设计的所有敏化剂都是对称的,并具有两个全氟苯基端基,它们可以在TiO 2表面上形成稳定的不可水解键。通过咔唑基和苯并噻二唑基单元的交替实现了在UV-Vis区域的广泛吸收和低带隙能级。所有染料及其相应的光阳极均通过各种互补技术进行了表征,包括循环伏安法测量和染料敏化太阳能电池测试中的敏化能力。
