Triazole bridged novel donor–acceptor dendrimers with triphenylamine as the core and benzoheterazole as the surface unit have been synthesized by click chemistry via a convergent approach. All the dendrimers exhibited excellent optical and electrochemical properties, as supported by DFT calculations. Lower generation dendrimers exhibit better current-generating capacity and also show better power conversion
三唑桥联的新型供体-受体树枝状大分子,以三苯胺为核心,苯并杂唑为表面单元,是通过点击化学通过收敛方法合成的。所有的树枝状聚合物均表现出优异的光学和电化学性能,这得到DFT计算的支持。当用作染料敏化太阳能电池的添加剂时,低代树状聚合物表现出更好的电流产生能力,并且还表现出比高代树状聚合物更好的功率转换效率。
