摘　　要：研究了一种新型的芴与咔唑交替共聚合物材料的电致发光(EL)特性,制备了2种不同结构的器件,分别为indium-tin-oxide(ITO)/polymer/tris-(8-hydroxyquinoline)-alumium(Alq3)/Mg:Ag和ITO/polymer/bathocu-proine(BCP)/Alq3/Mg:Ag。实验结果表明;前者发射绿色光,为Alq3的本征发光,聚合物起空穴传输层(HTL)的作用;后者发射蓝色光,EL谱与聚合物材料的光致发光(PL)谱一致,说明这种共聚物除了可用做空穴传输材料外,本身亦可做为优良的OLED蓝色发光材料。The electroluminescent（EID characteristics of a novel fluorene/carbazole copolymer were studied. Two different devices with the structure of indium-tin-oxide（ITO）/polymer/tris-（8-hydroxyquinoline）-alumium（Alqa ）/Mg：Ag and ITO/ polymer/bathocuproine（BCP） / tri- （8-hydroxyquinolino） -aluminum Alq3 / Mg： Ag were fabricated. The results demonstrated that the former device emitted green light, which was in accordance with the intrinsic luminance of Alq3, and the polymer played the role as hole transporting layer;the lattem had blue light emission,and its EI. spectrum conformed with the photoluminescence（PL） spectrum of copolymer. It indicates that this copolymer can he used as hole transporting rnaterial,and as high performance blue light emitting material for OLEDs.
