近年來小分子型發光錯合物研究隨著OLED的發展而倍受重視,除了在可見光區具有高效率的螢光外,製程簡單、價格便宜及高溫穩定性也都是值得深入研究的特性。其中以Alq3的應用最廣且最為人知,它的螢光發光波長在520 nm,是綠光。改變不同金屬觀察在螢光光譜上的變化及試著找出不同配位基與金屬配位,以期能夠找出新的藍光材料,是一個努力的方向,而在本篇論文中,我們則是試著嘗試借由取代基的影響,希望將它的發光波長大幅藍位移到藍光區,並探討其最有效合成路徑及材料性質的研究,進而找出便宜且容易大量合成並具藍色螢光之螢光材料。
In recent years, research into low molecular weight complexes as electroluminescent material in organic light emitting diodes (OLED) have attracted significant interest, with focus being paid into improving its luminescence efficiency, ease and cost of synthesis, and thermal stability. Among the myriad of known complexes with potential application in this area, tris-(8-hydroxyquinoline) aluminum (Alq3) have become one of the most popular complex used in OLEDs due to its good thermal stability and luminescence properties. Alq3 is a green light emitting material with a �釽ax of 520 nm.

Blue electroluminescent materials are essential for the development of full-color displays. This thesis describes the research of achieving this by the use of functionalized 8-hydroxyquinolines as ligands in the electroluminescent complex. By systematically installing electron donating groups onto 8-hydroxyquinoline, analogues of Alq3 were generated which possessed �釽ax greatly blue-shifted as compared to its parent. With a focus on possible industrial application of the newly generated OLEDs, a synthetic route amenable for such an endeavor was developed to facilitate the bulk generation of these newly developed blue light emitting devices.
