Abstract

Abstract A series of heteroleptic bis-cyclometalated iridium (III) complexes,[Ir (cpbi) 2 (H 2 dcbpy)][PF 6](1),[Ir (pbi) 2 (H 2 dcbpy)][PF 6](2), and [Ir (mpbi) 2 (H 2 dcbpy)][PF 6](3), where pbi= 1, 2-diphenylbenzimidazole, cpbi= 2-(4-chlorophenyl)-1-phenylbenzimidazole, mpbi= 2- (3, 4-dimethoxyphenyl)-1-phenylbenzimidazole, and H 2 dcbpy= 2, 2′-bipyridine-4, 4′- dicarboxylic acid has been synthesized and characterized by elemental analysis, 1 H, 31 ...
