A new red phosphorescent iridium(Ⅲ) complex, (DMP-MDCPQ)Ir(tmd) was synthesized for highly efficient red emitter of the organic light-emitting diode(OLED). The main ligand consisted of electron-donor (3,5-dimethylbenzene) and electron-acceptor (4-methyl-7,8-dihydro-6H-cyclopenta[g]quinoline) was synthesized by suzuki coupling reaction. The iridium(Ⅲ) complex based on main ligands and 2,2,6,6-tetramethyl-3,5-heptanedione (tmd) ancillary ligand were synthesized by Nonoyama reaction. Their luminescence property was investigated by UV-visible spectroscopy and photoluminescence (PL) spectroscopy. The OLEDs device was manufactured by spin-coating and vaccum deposition. This OLEDs device was characterized by investigation of current density-voltage-luminance (J-V-L), current efficiency, power efficiency, external quantum efficiency (EQE), EL spectrum. The iridium(Ⅲ) complex will be used as a solution process dopant for the hybrid OLED device. |
