| 英文摘要 | [(aryl-ppy)pt(acac)] (ppy = 2-phenylpyridine, acac = acetylacetonato) derivatives with triphenylamine (tpa) substituents on the ppy ligand have been prepared. the tpa fragment is either directly cyclometallated (pt-1) or attached to the ppy ligand through a c-c single bond (pt-2) or a novel alpha-diketo group (pt-3). all the complexes show room-temperature phosphorescence in fluid solution with emission bands in the range of 530-590 nm, which are red-shifted relative to the model complex [ppypt(acac)] (lambda(em) = 486 nm). this emission colour tuning effect is attributed to either an elevated homo energy caused by electron-donating tpa substituents on the ppy ligand or a decreased lumo energy caused by the electron-trap effect of electron-withdrawing substituents; both result in a smaller homo-lumo energy gap and thus red-shifted emission. the complexes show extended luminescence lifetimes (tau = 3.0-5.5 mu s) relative to the parent complex [ppypt(acac)] (tau = 2.6 mu s). the luminescent oxygen-sensing properties of the complexes were studied in solution and polymer films. white light emission was observed with an oled device fabricated with complex pt-3 with cie coordinates of (0.32, 0.32). |
