Abstract:
A new alternative copolymer composed of fluorene and quinoxaline units having benzothiadiazole groups in the side chain was prepared and used as a green emitter for polymeric light‐emitting diodes to give a device emitting pure green color at about 520 nm with a chromaticity coordinate of (x = 0.32, y = 0.59), matching the NTSC 1979 standard green color (x = 0.31, y = 0.595) very well.
