A kind of self-host blue-green phosphorescent Ir(III) complexes [(CzPhBI)2Ir(tfmptz), (CzPhBI)2Ir(tfmpptz) and (CzPhBI)2Ir(fpptz)] was designed and synthesized. CzPhBI, tfmptz, tfmpptz and fpptz were 9-[6-(2-phenyl-1-benzimidazolyl)hexyl]-9-carbazole, 2-(5-trifluoromethyl-1,2,4-triazolyl)pyridine, 2-[5-(4-trifluoromethyl)phenyl-1,2,4-triazolyl]pyridine and 2-[5-(4-fluoro)phenyl-1,2,4-triazolyl]pyridine, resp. The structures were confirmed by NMR (1H NMR and 19F NMR) and elemental anal. Photophys. properties were investigated. Electroluminescent performance of Ir(III) complexes were characterized by fabricating the non-doped devices with the configuration of indium tin oxid (ITO) | N,N’-bis-(1-naphthalenyl)-N,N’-bis-phenyl-(1,1′-biphenyl)-4,4′-diamine (NPB) (30 nm) | 4,4′-Bis (9-carbazolyl)-1,1′-biphenyl (CBP) (15 nm) | Ir complexes (30 nm) | 1,3,5-tris (1-phenyl-1H-benzo[d]imidazol-2-yl) benzene (TBPI) (30 nm) | LiF (1 nm) Al (100 nm). The maximum luminance of (CzPhBI)2Ir(tfmpptz) complexes was 6913 cd/m2 and the maximum luminous efficiency achieved 13.9 cd/A.
