Blue, Green, and Red Light Emission of 1,8-Carbazole-based Conjugated Polymers

Blue, green, and red light emitting conjugated copolymers based on the 1,8-linked carbazole unit were synthesized by the Sonogashira polycondensation between the 1,8-diethynylcarbazole derivative and arylene dibromide comonomers. The mixture of three polycarbazoles at a suitable molar ratio provided the white light emission in solutions.
