[Synthesis and characterization of phenyl-acetylmethylene sulfoxide complexes with light rare earth and fluorescence spectrum of Eu(III) complex].
Five solid complexes of phenyl-acetylmethylene sulfoxide(L) with light rare earth (La, Pr, Nd, Sm, Eu) were synthesized and characterized. Elemental analysis and molar conductivities show that the complexes have a composition of RE(ClO4)3 x L5 x 2H2O; two ClO4 anions coordinated with rare earth ions and the other did not. IR spectra suggested that the ligand coordinated with RE3+ by oxygen atom in sulfinyl group, and the oxygen atom in carbonyl group did not bond. The phosphorescence and 1H NMR and TG-DTA of the ligand and complexes were determind. Fluorescence spectra of Eu(III) complex with the sulfoxide indicated that the complex has no symmetrical center. All the complexes have good solubility.
