摘要
A series of iridium complexes with 2,5-diaryl-[1,3,4]-oxadiazole ligands were synthesized and their electrochemical, photophysical, and electroluminescent (EL) properties studied. It was found that electron-withdrawing or donating substituents on the phenyl ring affected the emission maxima. Complex 3, iridium(IR) bis(2,5-bis-(2-hydroxyphenyl)-[1,3,4]oxadiazolato-C-2, N-3) (acetyl acetonate), was characterized by single-crystal X-ray structural determination. Three organic light emitting diodes devices were fabricated, which showed stable green-yellow luminescence. (C) 2007 Elsevier Ltd. All rights reserved.
