设计并成功合成了两个系列的不同取代基的（dfppy）（2）Ir（L（N ^O））配合物，研究了辅助配体上取代基对配合物物理和电化学性质的影响.结果表明，L（N^O）上的-OMe给电子基团使（dfppy）（2）Ir（L（N^O））的PL量子效率提高，-CF（3）和-F吸电子基团使PL量子效率降低.
Two series of (dfppy)(2)Ir(L(N^O)) with different substituents were designed and successfully synthesized and the effect of substitution at the ancillary ligand on the photophysical and electrochemical properties of (dfppy)(2)Ir(L(N^O)) were investigated. The results indicate that the electron-donating group of -OMe at L(N^O) increases the PL quantum efficiencies of (dfppy)(2)Ir(L(N^O)) and the electron-withdrawing groups of -CF(3) and -F lower the PL quantum efficiencies.
