摘要: 以二(二苯基磷酰)胺(Htpip)作为辅助配体，与主配体2-(2，4-二氟苯基)异喹啉和2-(4-三氟甲基苯基)异喹啉合成了红光铱磷光配合物Ir(dfpiq)₂tpip和Ir(tfmpiq)₂tpip并得到了晶体结构。在CH₂Cl₂中发射光谱主要是MLCT发射，峰位置分别为622和600nm，量子效率分别为15%和17%，而HOMO/LUMO能级分别是-4.80/-2.58和-4.73/-2.57eV。在1150~1300(V·cm^-1)_1/2电场范围，Ir(dfpiq)₂tpip的电子迁移率为6.61~8.49×10^-6cm²·V^-1·s^-1，Ir(tfmpiq)₂tpip的电子迁移率为6.08~6.61×10^-6cm²·V^-1·s^-1。ITO/TAPC(60nm)/Ir-complex(15wt%)：CBP(50nm)/TPBi(60nm)/LiF(1nm)/Al(100nm)中基于Ir(dfpiq)₂tpip的器件最大安培效率和功率效率分别为4.71cd·A^-1和1.82lm·W^-1，12.0V时达到的最大亮度为18195cd·m^-2。基于Ir(tfmpiq)₂tpip的器件最大安培效率和功率效率分别为3.47cd·A^-1和1.51lm·W^-1，12.4V时达到的最大亮度为14676cd·m^-2。

Abstract: 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.
