A cyclometallated IrⅢ-μ-chloro-bridged dimer was synthesized by the reaction of a trifluoroacetylphenyl quinoline derivative and IrCl3. Then bicyclometalated iridium complex Ir(tfapq)2pic was synthesized by the reaction between dimer and picolinic acid. Ir(tfapq)2pic emitted a strong phosphorescence centered at 584 nm in a CH2Cl2 solution. Its lifetime is 1.211 μs and quantum yield is approximately 0.846 in a CH2Cl2 solution. Compared with the unmodified iridium complex, Ir(tfapq)2pic have a blue shift emission wavelength, sharp peak, higher quantum yield and shorter lifetime. The HOMO energy level is -5.405 eV and LUMO is -3.277 eV, which both lower than that of unmodified iridium complex and the greater energy band. The 10% weight loss temperature of Ir(tfapq)2pic is 301 ℃, which 50 ℃ higer than that of unmodified iridium complex. The organic light-emitting device based on Ir(tfapq)2pic (2wt% doped in PVK-PBD film) exhibits the best efficiency. It's peak electrophosphorescence wavelength is 594 nm. Its maximum external quantum efficiency is 12.65% and the corresponding efficiency is 22.14 cd·A-1. The maximum luminance is 8 571 cd·m-2. The turn-on voltage is 7.3 V with the Commission Internationale de L'Eclairage (CIE) coordinates of (0.58, 0.40).
