The synthesis, electronic properties, and performance in dye-sensitized solar cells (DSSCs) of four cone-shaped organic dyes (ITD, ITD-Th, ITD-Hx, and ITD-OM) containing the isotruxene π-scaffold are reported. Selective substitution of the unsymmetrical isotruxene core with two diarylamino donors and one cyanocarboxylic acid acceptor was achieved by using a prefunctionalized dibromoisotruxene building
四种锥形有机染料(ITD,ITD-Th,ITD-Hx和ITD-OM)的合成,电子性质以及在染料敏化太阳能电池(DSSC)中的性能报道了含有异特鲁烯π-支架的)。通过使用预官能化的二溴异丁烯结构单元,可以用两个二芳基氨基供体和一个氰基羧酸受体选择性取代不对称异丁烯核心。邻-对-支化异戊二烯核可实现供体与受体之间的强电子耦合,从而导致红移吸收曲线具有明显的电荷转移特性。四种异戊二烯染料均在循环伏安图中显示可逆的阳极波,同时具有适用于DSSC的HOMO和LUMO电位。用这些锥形有机染料制成的DSSC表现出高的开路电压(0.67-0.76 V)和填充因子(0.67-0.72),功率转换效率(η)高达5.45%,
