Synthesis and Fluorescence Properties of New Europium (III) and Terbium (III) Complexes with N-(3-methoxyl–phenyl)ketoacetamide

Abstract:

A β-diketonate-type ligand, N-(3-methoxyl–phenyl)ketoacetamide (L), and its complexes with europium (III) and terbium (III) were synthesized. The ligand and complexes were characterized by elemental analysis, IR spectra, ¹HNMR spectra, mass spectra and luminescent spectra. The complexes were characterized by elemental analysis, IR spectra. The stoichiometry of metal-to-ligand in the complexes also was confirmed by the fluorescence behavior of the ligand and complexes in CH₃CH₂OH solution. In addition, the fluorescence properties of complexes in DMF, CH₃OH, CH₃CH₂OH, acetone and CHCl₃ were investigated. The characteristic fluorescence of terbium (III) was assigned.
