Abstract

A novel π-conjugated small molecule VNCO, 2, 5-bis {3′-[3 ″-vinyl-9 ″-(α-naphthyl) carbazolyl] phenyl}-1, 3, 4-oxadiazole, containing hole-transporting carbazole moieties, electron-injecting 1, 3, 4-oxadiazole moieties and chromophore naphthalene was designed and synthesized by Wittig reaction of 2, 5-bis (3-tolylene-triphenylphosphonium bromide)-1, 3, 4-oxadiazole and 3-formyl-9-(α-naphthyl) carbazole. The UV–vis absorption, ...
