This invention provides a new electroluminescent conjugated polymers grafted with highly efficient phosphorescent organometallic complexes (such as iridium, platinum, osmium, rubidium, etc.) and charge transport moieties (such as oxadiazole, thiadiazole, triazole, pyridine, pyrimidine, substituted or non-substituted tertiary arylamines, substituted or non-substituted quarternary arylammonium salts, substituted or non-substituted tertiary heterocyclic aromatic amines, substituted or non-substituted quarternary heterocyclic aromatic ammonium, etc.). The emissive polymers (fully conjugated or limited conjugating length) covering the full visible range can be prepared. The polymeric light emitting diodes with these materials can be used as indicators, light source and display for cellular phones, digital camera, pager, portable computer, personal data acquisition (PDA), watch, hand-held videogame, billboard, etc.
该发明提供了一种新的电致发光共轭聚合物,其搭载高效的磷光有机金属络合物(如铱、铂、锇、铷等)和电荷传输基团(如氧化二唑、噻二唑、三唑、吡啶、嘧啶、取代或非取代的三级芳香胺、取代或非取代的季铵芳香基盐、取代或非取代的三级杂环芳香胺、取代或非取代的季杂环芳香铵等)。可以制备覆盖整个可见光范围的发射聚合物(完全共轭或有限共轭长度)。使用这些材料制作的聚合物发光二极管可以用作手机、数码相机、寻呼机、便携式电脑、个人数据采集器(PDA)、手持视频游戏、广告牌等的指示器、光源和显示器。
