In this paper, we prepared the compond [2-(2,4-difluorobenzene)pyridine-C2,N'](acetylacetone)Ir(III) Ir(dfppy)2(acac) by reaction of (dfppy)2Ir(μ-Cl2)Ir(dfppy)2 and acetylacetone, using one procedure under alkaline condition. This compomnd is a kind of high-performance phosphorescent material. Molecular structure of the product was confirmed by 1H NMR,13C NMR,IR and single crystal X-ray diffraction. And we investigate the photophysical properties using UV-vis and PL. We get the conclusion that Ir(dfppy)2(acac) is octahedral coordination compound with electric neutrality, and the average bond lengths are Ir-O 0.2160(14) nm, Ir-C 0.1998(11) nm, Ir-N 0.2030(15) nm, also we found that strong blue light excited at 484 nm. The yield was 90% and purity was 99.70%. The reaction is favorable for mass product of compond Ir(dfppy)2(acac). |
