Provided are a blue-light-emitting iridium complex, an iridium complex monomer, a phosphorescent polymer, and an organic electroluminescent device using same. The blue-light-emitting iridium complex contains a ligand having a low electron density structure, such as triazole or tetrazole. The iridium complex monomer containing a ligand having a polymerizable vinyl group produces a blue phosphorescent polymer through the polymerization with carbazole derivatives. The organic electroluminescent device comprises a first electrode, a second electrode, and a light-emitting layer interposed between the first electrode and the second electrode, wherein the light-emitting layer contains the above-described iridium complex or polymer containing the iridium complex.
提供了一种蓝光发射的铱配合物、一种含有可聚合乙烯基团的铱配合物单体、一种磷光聚合物,以及一种使用上述铱配合物或含有铱配合物的聚合物的有机电致发光器件。所述蓝光发射的铱配合物包含具有低电子密度结构的配体,例如三唑或四唑。所述含有可聚合乙烯基团的铱配合物单体通过与咔唑衍生物的聚合产生一种蓝色磷光聚合物。所述有机电致发光器件包括第一电极、第二电极,以及设置在第一电极和第二电极之间的发光层,其中发光层含有上述铱配合物或含有铱配合物的聚合物。
