Abstract
本發明提供一種共軛發光的高分子材料，側鏈含有磷光有機金屬(如銥(Ir)、鉑(Pt)、鋨(Os)、銣(Rb)等重金屬)錯合物，以及含有電荷傳輸基團(如噁二唑、噻二唑、三唑、吡啶、嘧啶、取代或非取代芳香族叔胺、取代或非取代芳香族季胺鹽、取代或非取代雜環芳香族叔胺、取代或非取代雜環芳香族季胺鹽)，所得到的高分子材料可發出涵蓋可見光區不同光色的光如紅、黃、綠、藍及白等，並可用於製作單層及多層發光二極體等元件。本發明所製得之發光二極體可應用於指示器、照明設備及各種顯示器例如行動電話、數位照相機、呼叫器、筆記型電腦、PDA、鐘錶、掌上型遊樂器、廣告看板等。
This invention provides a new electroluminescent conjugated polymers grafted with highly efficient phosphorescent organometallic complexes (such as indium, 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 quartemary arylammonium salts, substituted or non-substituted tertiary heterocyclic aromatic amines, substituted or non-substituted quartemary 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 (PLED) 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.
