Abstract

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 efficiency than higher generation dendrimers when used as additives in dye-sensitized solar cells.
