| 英文摘要 | Three novel europium complexes, Eu-L, EuL(3)phen and EuL2 (TPPO)(2)NO3, were synthesized (HL = phenylglyoxylic, phen= 1, 10-phenanthroline, and TPPO = triphenyl phosphine oxide). The complexes were characterized by elemental analysis, conductivity, IR, and H-1 NMR. The IR spectra indicated that all the complexes havea a larger Delta v (v(as)(CO2-)-v(S)(CO2-) than that of NaL, and carboxylate ions in the phenylglyoxyate coordinated as unidentate ligands. And alpha-aeto also ooordinated with the europium ions. In H-1 NMR, the signals of hydrogens in the phenylglyoxyate shifted toward upfield, and those in phen or TPPO slightly shifted. The excitation and emission spectra were recorded at room temperature, and the excitation spectra showed that the optimum excitation wavelengths were 374.0, 358.2 and 383.4 nm, Five emission bands of the complexes due to D-5(0)-F-7(0), D-5(0)-F-7(1), D-5(0)-F-7(2), D-5(0)-F-7(3) and D-5(0)-F-7(4) transitions were observed in the region of 550-720 nm (Eu-L: 577.8, 590.2, 614.0, 648.4 and 695.4 EuL(3)phen: 578.0, 588.4, 591.6, 611.2, 617.0, 649.4, 687.6 and 698.6 nm; EuL2 (TPPO)(2)NO3 : 577.8, 590.4, 614.6, 649.2 and 697.6 nm). The emission intensities of europium ions were obviously sensitized by TPPO. |
