Chiral dendritic architectures with benzothiazole as surface group, 1,2,3-triazole as a bridging unit, and (S)-BINOL (1,1-bi-2-naphthol) as a core unit were synthesised in good yields via a convergent synthetic strategy. The chiroptical properties of the dendrimers revealed that the specific rotation increased in the order of dendrimers 4 > 3 > 2 > 1. All the dendrimers showed excellent optical and electrochemical response, and hence would find application in dye-sensitised solar cells.
通过聚合合成策略,以
苯并噻唑为表面基团、
1,2,3-三唑为桥接单元、(S)-BINOL(1,1-联-
2-萘酚)为核心单元的手性树枝状结构以良好的收率合成。树枝状聚合物的光电性质表明,比旋转率按照树枝状聚合物 4 > 3 > 2 > 1 的顺序增加。所有树枝状聚合物都显示出优异的光学和电
化学响应,因此可应用于
染料敏化太阳能电池。
