A new beta-diketonate-type ligand, N-(2-amino-6-methyl-pyridinyl)ketoacetamide (L) and its complexes with europium (III) and terbium (III) were synthesized. The complexes were characterized by elemental analysis, infrared spectra and conductivity. The europium (III) and terbium (III)-ions were found to coordinate to the CO oxygen atoms and pyridine nitrogen atoms. The fluorescence properties of these complexes in solid, DMF and CH3OH were studied. The solvent factors influencing the fluorescent intensity are discussed.
合成了一种新型β-二酮类配体N-(2-氨基-6-甲基吡啶基)酮乙酰胺(L)及其与铕(III)和铽(III)的配合物。通过元素分析、红外光谱和电导率对配合物进行了表征。发现铕(III)和铽(III)离子与羰基氧原子和吡啶氮原子配位。研究了这些配合物在固体、N,N-二甲基甲酰胺和甲醇中的荧光性质。讨论了影响荧光强度的溶剂因素。
