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, respectively. The structures were confirmed by nuclear magnetic resonance(1H NMR and 19F NMR) and elemental analysis. Photophysical 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.
