Abstract
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 □max 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 □max 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.
