| Abstract: An IrⅢ complex [Ir(dfppy)2(bpm)]Cl was synthesized with 2-(4′,6′-difluorophenyl)pyridine (dfppy) as cy-lcometalated ligand and 2,2′-bipyrimidine (bpm) as ancillary ligand. It was characterized by 1H NMR, mass spectr-ometry, element analysis and FTIR spectra, and its crystal structure was measured. At the same time, the forma-tion of this complex was discussed by the crystal structure of mediated complex [Ir(dfppy)2(bpm)]+[Ir(dfppy)2(Cl)2]-. The UV-Vis absorption and photoluminescence spectra of [Ir(dfppy)2(bpm)]Cl were recorded. The emission at room temperature peaked at 609 nm, and it was supposed that the phosphorescence might originate from the mixture of the MLCT (metal-to-ligand charge transfer) transition and ligand-centered π → π* transition. CCDC: 671986, [Ir(dfppy)2(bpm)]Cl; 671987, [Ir(dfppy)2(bpm)]+[Ir(dfppy)2(Cl)2]-. |
