摘要：

Novel phosphorescent bis-cyclometallated iridium(III) complex based on the quinoline and 2-phenyl-1,2,3-triazole moieties fused at the f edge of quinoline has been synthesized. The iridium complex exhibits yellow phosphorescence emission of high quantum yield (78% in solution) and microsecond lifetime (2.6 mu s), indicating radiative recombination to originate mainly from the triplet metal-to-ligand charge transfer excited state due to strong spin-orbit coupling of the iridium. The revealed properties show a great promise for the new iridium complex to be used in efficient yellow phosphorescent organic light emitting diodes. (c) 2008 Elsevier B.V. All rights reserved.
