Red phosphorescent iridium(III) complexes, (TPIQ)2Ir(acac) and (TPIQ)2Ir(ppy), based on 1-(4-(trimethylsilyl)phenyl)isoquinoline (TPIQ) as the cyclometalated main ligand and either acetylacetone (acac) or 2-phenylpyridine (ppy) as an ancillary ligands, were synthesized for solution-processed organic light-emitting diodes (OLEDs). The Ir(III) complex, (PIQ)2Ir(acac), which consists of 1-phenylisoquinoline (PIQ) as the main ligand and acac as the ancillary ligand, was also synthesized as a reference. The photophysical, electrochemical, and electroluminescent (EL) properties of Iridium(III) complexes were investigated. Red OLED using (TPIQ)2Ir(ppy) as an emitter exhibited significantly more improved a full-width at half-maximum (FWHM) by introduction of ppy as an ancillary ligands. The EL spectrum of (TPIQ)2Ir(ppy) exhibited emission maximum at 640 nm with a full-width at half-maximum (FWHM) of 113 nm and Commission Internationale de L'Eclairage (CIE) coordinates of (0.68, 0.32) at 1000 cd/m2. The device with 7 wt% doping concentration of (TPIQ)2Ir(ppy) exhibited maximum luminance of 6,296 cd/m2, maximum luminous efficiency of 15.93 cd/A, power efficiency of 5.26 lm/W, and external quantum efficiency of 5.45 %, respectively.
