| 英文摘要 | FT-IR and Raman vibrational spectra and electronic emission spectra have been recorded for enantiomers of europium complexes with DBM: dibenzoylmethanate 1,2, and TTFA: 2-thenoyltrifluoroacetonate 3,4, employing the chiral ligands L(SS)(+)- and L(RR)(-)-4,5-pinene bipyridine. Contrary to the previously published X-ray data, where geometrical differences were stated to occur for particular enantiomers, the vibrational (and the emission) spectra of the individual optical isomers of a complex are not distinguishable. Using excitation into the Eu(3+) (5)D(2) multiplet term, the emission intensity is weak from (5)D(1), whereas a complex structure is observed for the (5)D(0) -> (7)F(J) transitions. Features in the vibronic sidebands exhibit similar derived vibrational energies to those observed in the Raman spectra. Fittings of 25 4f(6) crystal-field energy levels of 2 and 4 have been attempted with some approximations concerning the local Eu(3+) environments. The (5)D(0) emission lifetimes are monoexponential and are 0.5 (1,2) and 0.9 ms (3,4) at room temperature. (C) 2008 Elsevier B.V. All rights reserved. |
