    摘要: An organic electroluminescent (EL) polymer for a light emitting diode in accordance with the present invention is PDPCVz which is prepared by combining a dialkyl substituted phenylene moiety and a carbazole moiety. Another organic EL polymer is PPOPPD which is prepared by combining an oxadiazole moiety and a phenylene moiety. In the present invention, a polymer blend of said PDPCVz and PPDPPO is used for an organic EL polymer. The organic EL polymer according to the present invention is applied to a light emitting layer of a light emitting diode having a cathode/light emitting layer/anode structure, a cathode/buffer layer/light emitting layer/anode structure, or a cathode/hole transporting layer/light emitting layer/electron transporting layer/anode structure. Each of said PDPCVz and PPDPPO can be blended with conventional polymers such as polystyrene, polycarbonate, polyacrylate, polymethylmethacrylate, polyvinylcarbazole, polyimide, liquid crystalline polymer, etc. The EL polymers according to the present invention can be blended with a lower molecular fluorescent dye.
