چکیده انگلیسی
A series of phosphorescent Ir(III) complexes 1-4 were synthesized based on aryl(6-arylpyridin-3-yl)methanone ligands, and their photophysical and electroluminescent properties were characterized. Multilayer devices with the configuration, Indium tin oxide/4,4â²,4â³-tris(N-(naphthalene-2-yl)-N-phenyl-amino)triphenylamine (60Â nm)/4,4â²-bis(N-(1-naphthyl)-N-phenylamino)biphenyl (20Â nm)/Ir(III) complexes doped in N,Nâ²-dicarbazolyl-4,4â²-biphenyl (30Â nm, 8%)/2,9-dimethyl-4,7-diphenyl-phenathroline (10Â nm)/tris(8-hydroxyquinoline)-aluminum (20Â nm)/lithium quinolate (2Â nm)/ Al (100Â nm), were fabricated. Among these, the device employing complex 2 as a dopant exhibited efficient red emission with a maximum luminance, luminous efficiency, power efficiency and quantum efficiency of 16200Â cd/m2 at 14.0Â V, 12.20Â cd/A at 20Â mA/cm2, 4.26Â lm/W and 9.26% at 20Â mA/cm2, respectively, with Commission Internationale de l'Ãnclairage coordinates of (0.63, 0.37) at 12.0Â V.
