We have synthesized series of new phosphorescent cyclometalated iridium (III) complexes Ir(Br-DPQ)2(acac), with 2-(4-bromo-phenyl)-4-phenyl-quinoline (Br-DPQ) ligand and Ir(Cl-BrDPQ)2 (acac) with 4-chloro-2-(4-bromophenyl)-4-phenyl quinoline (Cl-BrDPQ) ligand. Synthesized complexes and ligands were characterized by X-ray diffraction, elemental analysis, infrared spectroscopy (FTIR) and thermal analysis (TGA/DTA,DSC). UV-vis absorption and emission spectroscopy, photoluminescence (PL) emission peaks of Br-DPQ and Cl-BrDPQ in different solvents such as chloroform, dichloromethane, THF, acetic acid and formic acid is between 425 to 460 nm The metal complex display pure red luminescence in solution and in powder states in the range of λmax 615-651 nm. The iridium metal complex Ir(Br-DPQ)2(acac) where (Br-DPQ=2-(4-bromo phenyl)-4-phenyl quinoline shows strong 1MLCTand 3MLCT absorption peak at, 227, 265, 283, 346, and 432 nm in tetrahydrofuran (THF) solution and Ir(Cl-BrDPQ)2(acac) where (Cl-BrDPQ)=4chloro2-(4-Bromo phenyl)-4-phenyl quinoline shows strong 1MLCTand 3MLCT absorption peak at 262, 330, 438, 476, 505 and 535 nm in dichloromethane solution. It is suggested that the synthesized iridium complexes may be efficiently used as the emissive dopants in phosphorescent organic light-lmitting devices (PhOLEDs). Thus these complexes could be promising candidates for potential applications in Phosphorescent organic light-emitting diodes PhOLEDs, light-emitting electrochemical cells and solid-state organic lighting applications.
