【Abstract】 A kind of self-host blue-green phosphorescent Ir( Ⅲ) complexes [( Cz Ph BI)2Ir( tfmptz),( Cz Ph BI)2Ir( tfmpptz) and( Cz Ph BI)2Ir( fpptz) ] was designed and synthesized. Cz Ph BI,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 and19 F 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) │Li F( 1 nm) │Al( 100 nm). The maximum luminance of( Cz Ph BI)2Ir( tfmpptz) complexes was 6913 cd / m2 and the maximum luminous efficiency achieved 13. 9 cd / A.更多还原
