摘　　要：以1-苯基异喹啉(piq)为主配体,以3-甲基-2-吡啶甲酸(mecid)为辅助配体合成了一种铱(Ⅲ)配合物Ir(piq)2(mecid)。采用元素分析、红外光谱、核磁共振谱分析和单晶X射线衍射对其化学组成和结构进行了表征。采用热失重(TGA)曲线分析了其热稳定性质,热分解温度为325℃。采用紫外-可见光谱和光致发光光谱对其光物理性质进行了分析。结果表明,化学组成为C_(37)H_(26)IrN_(3)O_(2),属于三斜晶系,P1/n空间群。晶胞参数为a=8.3130(4)nm,b=11.4866(5)nm,c=15.3737(7)nm,α=75.726(2)°,β=83.005(2)°,γ=88.785(2)°,V=1.4120(11)nm^(3),Z=2。光物理性质显示最大发射波长为618 nm,为红色发射的铱磷光配合物。An iridium(Ⅲ)complex Ir(piq)2(mecid)was synthesized with 1-phenylisoquinoline(piq)as the main ligand and 3-methyl-2-pyridinic acid(mecid)as the auxiliary ligand.By elemental analysis,infrared spectroscopy,nuclear magnetic resonance(NMR)spectroscopy analysis and single crystal X-ray diffraction on the chemical composition and structure characterization.The thermal stability was analyzed by thermogravimetric(TGA)curve,and the thermal decomposition temperature was 325℃.The photophysical properties were analyzed by UV-VIS and photoluminescence spectra.The results show that the chemical composition is C_(37)H_(26)IrN_(3)O_(2),belonging to the triclinic system and P1/n space group.Crystal cell parameters for a=8.3130(4)nm,b=11.4866(5)nm,c=15.3737(7)nm,α=75.726(2)°,β=83.005(2)°,γ=88.785(2)°,V=1.4120(11)nm^(3),Z=2.Photophysical properties show a maximum emission wavelength of 618 nm,which is a red-emitting iridium phosphor complex.
