| 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 C37H26IrN3O2, 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) nm3, Z=2. Photophysical properties show a maximum emission wavelength of 618 nm, which is a red-emitting iridium phosphor complex. |
