Abstract

Abstract A poly(arylene ether) containing hole-transporting tetraphenylbenzidine units and electron-transporting 1,3,4-oxadiazole units was synthesized and examined as an emitter layer in organic electroluminescent device. The device structure of glass substrate / indium-tin oxide / polymer / Mg:Ag was employed. The EL device exhibited blue green light originating from the polymer emitter layer with a maximum luminance of 26 cd/m2 at 12 volt.
