摘要
本文制备了一种D-(π-A)2结构的喹喔啉类染料,以长碳链的烷基苯修饰电子供体端,目的在于抑制电子复合并增加染料的可溶性,以双苯甲酸作为锚固基团,改善染料吸附稳定性。该染料通过简单的缩合、溴化、水解等反应即可制备,组装的电池器件转换效率达到了4.70%,这对于新型染料敏化剂的设计具有良好的指导意义。
We synthesized a D-（π-A）2 quinoxaline dye, in order to inhibit electron recombination and increase the solubility of dyes, we modified electronic donor with long carbon chain, in addition, we used dibenzoic acid as anchorage group, so that the dye adsorption stability can be improved. The synthetic method is very simple, it can be synthesized by suzuki coupling, condensation, bromination, hydrolysis and other reactions. The DSSC showed a PCE of 4.70%, this has good guiding significance for the design of new dye sensitizers.
