A series of new iridium complexes bearing pyrrylimine ligands, [(ppy)2Ir(N^N)] (ppy=2-phenylpyridine), were synthesized and characterized by 1H NMR, mass spectroscopy and elemental analysis. The reaction conditions of synthesis, UV-Vis absorption, photoluminescence and quantum efficiencies of the complexes were investigated. The results showed that the iridium complexes were obtained in good yields at room temperature using NaOAc as a base in dichloromethane. By changing the substituents in the pyrrylimine ligands, these complexes would have a range of luminescence wavelength from 507 to 606 nm and realize tuning from green to red. All of the iridium complexes in solution show high quantum efficiencies (0.25~0.95).

Key words: phosphorescent material, iridium complex, pyrrylimine, synthesis, luminescent property
