Description
本發明係關於新穎有機電場發光化合物及使用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,其具有之優勢在於,EL裝置係提供更寬之視角,更大之對比度以及更快之響應時間。有機EL裝置係由Eastman Kodak首先研發,其藉由使用小芳族二胺分子以及鋁錯合物作為形成發光層之材料[Appl.Phys.Lett.51,913,1987]。
決定有機EL裝置之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,由於磷光材料理論上對發光效率之提升為螢光材料之四(4)倍,磷光發光材料之發展業經得以廣泛研究。銥(III)錯合物作為磷光材料而廣為人知,包括雙(2-(2’-苯並噻吩基)-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)分別作為紅色、綠色及藍色材料。
迄今為止,4,4’-N,N’-二咔唑-聯苯(CBP)係傳統技術中最廣
為人知之用於磷光物質的主體材料。再者,使用浴銅靈(bathocuproine,BCP)及雙(2-甲基-8-羥基喹啉)(4-苯基苯酚)鋁(III)(BAlq)用於電洞阻擋層的有機EL裝置亦係已知者,日本先鋒公司(Pioneer)研發了採用BAlq衍生物作為主體材料之高效能有機EL裝置。
儘管此等材料係提供良好之發光特性,他們仍具有下述缺點:(1)由於他們的低玻璃轉化溫度及不良之熱安定性,可能於真空高溫沉積製程過程中出現降解。(2)有機EL裝置之功率效率係藉由[(II/電壓)×電流效率]給出,且功率效率係與電壓成反比。包含磷光主體材料之有機EL裝置係提供比包含螢光材料者高得多的電流效率(燭光(cd)/安培(A))。惟,其係具有高驅動電壓,因此,於功率效率(流明(lm)/瓦(W))方面不具優勢。(3)再者,有機EL裝置之操作壽命短,且發光效率仍需改良。
國際專利案公開第WO 2011/081423號揭露了經聯伸三苯基及茀基取代之咔唑化合物。惟,該化合物需要高驅動電壓,故不適用於商業化。
本發明之目的係提供一種有機電場發光化合物,該化合物係賦予裝置高發光效率及長操作壽命,且具有適宜之色座標;以及提供一種使用該化合物作為發光材料之具有高效率及長壽命的有機電場發光裝置。
本發明之發明人發現上揭目的係藉由下式1表示之有機電場
發光化合物達成:

S、P(=O)、Si及P之至少一個雜原子。
本發明之有機電場發光化合物係具有高發光效率及良好之壽命特徵,因此可提供具有長操作壽命之有機電場發光裝置。
此外,由於在本發明中使用的有機電場發光化合物對於傳輸電子高度有效,本發明使得製造不會結晶之裝置成為可能。再者,該等化合物係具有良好之層可形成性並改善該裝置之電流特徵。
因此,可製造具有降低之驅動電壓及提升之功率效率的有機電場發光裝置。
