Abstract

Two D–A–D-type low band gap organic dyes based on triphenylamine and benzoxadiazole/ benzothiadiazole, 4, 7-Bis {5-{4-{2-[4-(N, N-diphenylamino) phenyl]-1-nitrilethenyl} phenyl}-2- thienyl}-2, 1, 3-benzoxadiazole (BDNTBX) and 4, 7-Bis {5-{4-{2-[4-(N, N-diphenylamino) phenyl]-1-nitrilethenyl} phenyl}-2-thienyl}-2, 1, 3-benzothiadiazole (BDNTBT) were successfully synthesized. The properties of two compounds were investigated by density ...
