By introducing tetraphenylimidodiphosphinate (Htpip) as the ancillary ligand, two iridium complexes Ir(tfmpiq)₂tpip and Ir(dfpiq)₂tpip (dfpiq=2-(2,4-difluorophenyl)quinoline, tfmpiq=2-(4-(trifluoromethyl)phenyl)quinoline) have been synthesized. For the emission spectra in CH₂Cl₂ solution, the maximum peaks locate at 622 and 600 nm for Ir(tfmpiq)₂tpip and Ir(dfpiq)₂tpip with the quantum efficiencies of 15% and 17%, respectively. The HOMO/LUMO levels are calculated as-4.80/-2.58 and-4.73/-2.57 eV, respectively. Under electric field from 1150 to 1300 (V·cm^-1)_1/2, the electron mobilities in 60 nm Ir(tfmpiq)₂tpip and Ir(dfpiq)₂tpip layers are 6.61~8.49×10^-6 cm²·V^-1·s^-1 and 6.08~6.61×10^-6 cm²·V^-1·s^-1, respectively. The devices with the structure of ITO/TAPC(60 nm)/Ir-complex (15wt%): CBP (50 nm)/TPBi(60 nm)/LiF(1 nm)/Al(100 nm) were fabricated. The device based on Ir(dfpiq)₂tpip exhibited a luminance of 18195 cd·m^-2 at a driving voltage of 12.0 Vwith a maximum current efficiency (η_c) of 4.71 cd·A^-1 and a maximum power efficiency (η_p) of 1.82 lm·W^-1, respectively. While the device based on Ir(tfmpiq)₂tpip exhibited a luminance of 14676 cd·m^-2 at a driving voltage of 12.0 V with a maximum η_c of 3.47 cd·A^-1 and η_p of 1.51 lm·W^-1, respectively.
