Description
本發明係關於新穎有機電場發光化合物及包含該化合物之有機電場發光裝置。
電場發光(EL)裝置係自發光裝置,與其他類型之顯示器裝置相比,其在提供更寬視角、更高對比度及更快響應時間方面具有優勢。Eastman Kodak使用小分子芳香族二胺以及鋁錯合物作為形成發光層之材料而首次研發有機EL裝置[Appl.Phys.Lett.51,913,1987]。
確定有機EL裝置中發光效率之最重要因素係發光材料。迄今為止,螢光材料業經廣泛用作發光材料。惟,以電場發光機制之觀點看來,由於磷光材料理論上比螢光材料顯示具有高4倍的發光效率材料,故磷光發光材料之研發被廣泛研究。銥(III)錯合物業經作為磷光材料而廣為人知,包括分別作為紅色、綠色及藍色發光材料之雙(2-(2'-苯并噻吩基)-吡啶-N,C3')銥(乙醯丙酮)((acac)Ir(btp)2)、參(2-苯基吡啶)銥(Ir(ppy)3)及雙(4,6-二氟苯基吡啶-N,C2)吡啶甲酸銥(Firpic)。
發光材料(摻雜劑)可與主體材料組合使用,以改良顏色純度、發光效率及安定性。當使用主體材料/摻雜劑系統作為發光材料時,由於主體材料極大地影響該EL裝置之效率及效能,其選擇非常重要。
當下,4,4'-N,N'-二咔唑-聯苯(CBP)係最廣為人知之磷光發光主體材料。近來,日本先鋒(Pioneer)等研發了高效能有機EL裝置,其係採用已知作為電洞組當層材料之浴銅靈(BCP)以及雙(2-甲基-8-羥基喹啉)(4-苯基苯酚)鋁(III)(BAlq)作為主體材料。
儘管此等磷光主體材料提供良好之發光特徵,其仍具有下述缺陷:(1)由於他們的玻璃轉化溫度低且熱安定性差,他們可能於高溫真空沉積製程中劣化。(2)有機EL裝置之功率效率係藉由[(Π/電壓)×電流效率]而給出,且功率效率係與電壓成反比。儘管包含磷光主體材料之有機EL裝置提供比包含螢光材料者更高之電流效率(燭光(cd)/安培(A)),其仍需要高驅動電壓。因此在功率效率(流明(lm)/瓦(W))方面不存在實質優點。(3)再者,該有機EL裝置中之操作壽命短,且發光效率仍需改善。
同時,銅酞青(CuPc)、4,4'-雙[N-(1-萘基)-N-苯基胺基]聯苯(NPB)、N,N'-二苯基-N,N'-雙(3-甲基苯基)-(1,1'-聯苯)-4,4'-二胺(TPD)、4,4',4"-參(3-甲基苯基苯基胺基)三苯基胺(MTDATA)等係用作為電洞注入及傳輸材料。
惟,使用此等材料之有機EL裝置於量子效率及操作壽命方面有問題。此係因為,當於高電流下驅動有機EL裝置時,於陽極與電洞注入層之間出現熱應力。熱應力顯著降低該裝置之
操作壽命。再者,由於在該電洞注入層中使用之有機材料係具有非常高之電洞遷移性,電洞-電子電荷平衡可能被打破且量子產率(cd/A)可能下降。
世界專利公開案第WO 2009/148015號揭露了一種有機EL裝置用化合物,於該化合物中,雜芳基如咔唑、二苯并噻吩或二苯并呋喃係鍵結於藉由茀、咔唑、二苯并呋喃或二苯并噻吩與茚、吲哚、苯并呋喃或苯并噻吩稠合而形成之多環化合物機構的碳原子位置。
此外,美國專利申請案公開第2011/0279020 A1號揭露了一種用於有機電場發光裝置之化合物,於該化合物中,兩個咔唑部份係通過碳-碳單鍵鍵結。
惟,上揭參考文獻並未具體揭露其芳基胺或雜芳基胺係鍵結於藉由咔唑與茚、吲哚、苯并呋喃或苯并噻吩稠合而形成之多環化合物結構的氮原子位置。
