Paper Abstract

As we know, Strong fluorescent dyes are important light-emitting materials of OLED. 8-hydroxyl quinoline aluminum (Alq3) is one of the best electroluminescent materials with good film-formation and thermal, excellent electron-transporting ability. However Alq3 is mostly employed in OLED device for electron transport layer or host material by vacuum deposition. Because of its poor dissolubility in common organic solvent, and be easily recrystallized from the OLED device, the stability of OLED with Alq3 is decreased. To overcome such defects, we have designed and synthesized five kinds of Alq3 derivatives. Their chemical structures were elucidated by IR, 1HNMR and element analysis. Their photoluminescence (PL) and electroluminescence (EL) properties have been investigated and the relationships between molecular structures and light- emitting properties have been studied as well.
