Synthesis of novel dendrimers with benzothiazole as surface group and triazole as branching unit is achieved through click chemistry. The presence of more number of benzothiazole and triazole units increases the molar absorption coefficient and alters the fluorescence as well as electrochemical behaviors in the dendrimers. Dye-sensitized solar cell (DSSC) studies reveal that dendrimers with more number
通过点击化学合成了以苯并噻唑为表面基团和三唑为支化单元的新型树枝状大分子。大量苯并噻唑和三唑单元的存在增加了摩尔吸收系数,并改变了树枝状聚合物中的荧光以及电化学行为。染料敏化太阳能电池(DSSC)研究表明,苯并噻唑和三唑基团数量较多的树枝状聚合物比苯并噻唑和三唑基团数量较少的树枝状聚合物表现出更好的电流产生能力。树枝状聚合物2b显示出7.1%的最大电流转换效率(η)。
