Two new cyclometalated iridium(Ⅲ) complex (dpci)₂Ir(paz) and (dpci)₂Ir(taz) (dpci=3, 4-diphenylcinnoline, pazH=5-(2-pyridyl)-3-trifuoromethylpyrazole, tazH=5-trifuoromethyl-3-(pyridin-2-yl)-1H-1, 2, 4-triazole), were succ-essfully synthesized and characterized by NMR spectroscopy and high resolution mass spectrometry. The photo-luminescence spectra of (dpci)₂Ir(paz) and (dpci)₂Ir(taz) in PMMA (1%, w/w) show emission maximum at 616 and 612 nm, which are blue shifted compared to that of reference complex (dpci)₂Ir(pic) (pic=picolinate, 625 nm). The quantum yields of (dpci)₂Ir(paz) and (dpci)₂Ir(taz) are 51.9% and 32.5%, which are higher than that of (dpci)₂Ir(pic) (16.1%). After modification, the thermal stability of complexes are enhanced, and they can be used to prepare organic electroluminescent devices by evaporation method. OLED device using (dpci)₂Ir(paz) as dopant exhibited intense saturated red emission with CIE coordinates of (0.66, 0.34). The device has the best performance with a maximum external quantum efficiency of 2.7% and luminance efficiency of 8.5 cd·A^-1. The maximum luminance was 2 484 cd·m^-2. The device based on I(dpci)₂Ir(taz) exhibits the best efficiency. Its maximum external quantum efficiency is 5.5% and the corresponding efficiency is 14.5 cd·A^-1. The maximum luminance is 2 931 cd·m^-2.
