Blue electroluminescence from a copolymer containing oxadiazole units is reported. The copolymer is separated in the light emitting diode device from the ITO anode by an additional layer of polyaniline in order to increase the quantum efficiency, resulting an external quantum efficiencies of 0.1%, and an intensity of the blue emitted light of 40 cm/m 2 .
