Synthesis and Photoluminescence of a Novel Iridium Complex (BuPhOXD)2Ir(acac) with Unit of 1,3,4-Oxadiazole

Abstract

A novel cyclometalated iridium complex with 1,3,4-oxadiazole moiety was synthesized and characterized. Its UV and photoluminescent properties were studied. The strong UV absorption intensity around 462 nm attributed to spin-forbidden triplet metal-ligand charge transfer band and photoluminescence at 518 nm were observed. This indicated that achieved iridium complex could be used as an efficient electrophosphorescent material.
