摘　　要：利用新型的含有二唑基团PPV衍生物,制备了结构为ITO/PVK∶OPPV(2∶1质量比)/OXD(40nm)/Alq(20nm)/Al的器件,研究了该PPV衍生物的发光特性。结果表明:OPPV发光峰位于460nm,是一种蓝色电致发光聚合物材料。二唑基团的引入,改善了PPV衍生物的电子传输特性。The device with structure of ITO/PVK∶OPPV(2∶1 weight ratio)/OXD(40nm)/Alq(20nm)/Al was fabricated. Luminescent properties of a novel PPV derivative(OPPV) containing oxadiazole segments in main and side chains were studied. The peak of OPPV spectrum located at 460nm was a kind of material emitting blue light. The electron transport ability of OPPV was improved due to introducing oxadiazole groups.
