| 英文摘要 | Six heteroleptic cuprous complexes, [L(1)Cu(PPh(3))(2)](BF(4)) (1a), [L(1)Cu(DPEphos)](BF(4)) (1b), [L(2)Cu(PPh(3))(2)](BF(4)) (2a), [L(2)Cu-(DPEphos)](BF(4)) (2b), [L(3)Cu(PPh(3))(2)](BF(4)) (3a), and [L(3)Cu-(DPEphos)](BF(4)) (3b) = )L(1) = diphenyl(2-pyridyl)phosphane oxide, L(2) = diphenyl(8-quinolyl)phosphane oxide, (L)3 = diphenyl(2-pyridylmethyl)phosphane oxide, DPEphos = bis[2-(diphenylphosphanyl)phenyl] ether), were prepared and fully characterized. The electronic absorption spectra and quantum chemical calculations indicate that the lowest excited states of these complexes can be assigned to the metal-to-ligand charge transfer (MLCT) transition. In poly(methyl methacrylate) (PMMA) films, these complexes exhibit blue-green to orange emissions with long lifetimes ranging from 7.5 to 28.6 mu s. With wide energy-band gaps of 3.50 and 3.28 eV, complexes 3a and 3b emit efficiently in 20 wt.-% PMMA films with photoluminescence quantum efficiencies of 0.69 and 0.72, and emission maxima at 477 nm and 495 nm, respectively. Electroluminescent devices were fabricated with these N,O-based Cu(I) complexes as emitters. The best device performance, with a peak current efficiency of 4.9 cd/A, was obtained for 3b. |
