Chinese Abstract

本論文的目的在於研究與合成苯基異喹碄銥金屬錯合物,及將這些有機銥錯合物應用於有機電激發光紅光材料的應用上。此研究主要分為兩個部分:第一部分是利用有取代基的苯甲酸化合物與氨類 (amine) 縮合後,再以五氧化二磷 (P2O5) 在酸性條件下將化合物進行縮環反應,接著再利用二氧化錳 (MnO2) 將縮環後的化合物進行脫氫反應而得到最終產物“具有取代基的苯基異喹碄化合物”。第二部分則利用取得的各種不同取代基的苯基異喹碄化合物做為配位基,將其與銥金屬進行錯合反應而取得各種不同配位基的苯基異喹碄銥金屬錯合物。我們對這些銥錯合物進行了吸收波長、溶液態放光波長及做成有機發光元件的各種效能測試。實驗結果顯示,我們所合成的銥金屬錯合物的放光波長位於600 ~ 640 nm 之間,且在發光元件的應用上有不錯的發光效率。尤其是 (4’-opiq)2Ir(acac) 這個材料在11V 電壓操作下最大亮度可達32697 cd/m2,最大的能量效率 (Power efficiency, P. E.) 為6.58 lm/W,發光效率 (Luminous efficiency, L. E.) 為13.28 cd/A。這些銥錯合物具有被應用於有機電激發光材料的可能性。

English Abstract

Organic Light-Emitting Diodes (OLEDs) have potential for application in the flat panel display, and have received vast attention. This work focuse on synthesizing various substituent groups on phenyl-isoquinoline, and a series of red phosphorescent materials based on iridium complexes with these phenyl isoquinoline derivative ligands.  These iridium-phenyl isoquinoline complexes all have red emissions, and light-emitting devices based on these complexes all have good efficiencies.Especially, (4’-opiq)2Ir(acac) possesses the best efficiencies over the other iridium complexes. When operated at 11V, (4’-opiq)2Ir(acac) has a maximum luminescence about 32697 cd/m2, and a maximum power efficiency of 6.58 lm/W and a maximum luminous efficiency of 13.28 cd/A. The results suggest that these iridium complexes may serve as good red organic light-emitting materials.
