An amide-based 1,10-phenanthroline (phen) derivative and its complexes with europium(III) and terbium(III) ions were synthesized. The complexes were characterized by elemental analysis, infrared spectra and conductivity. The europium and terbium ions were coordinated by O atoms of C=O, Ar-O-C and N atoms of phen. The fluorescence properties of the complexes in THF, dioxane, MeCN and DMF were investigated. Under the excitation of UV light, these complexes exhibited characteristic fluorescence of europium and terbium ions. The solvent factors influencing the fluorescent intensity were discussed.
合成了一种基于酰胺的1,10-菲咯啉（phen）衍生物及其与铕（III）和铽（III）离子的配合物。通过元素分析、红外光谱和电导率对配合物进行了表征。铕离子和铽离子由C=O的O原子、Ar-O-C的O原子以及phen的N原子配位。研究了配合物在四氢呋喃、二氧六环、乙腈和N,N-二甲基甲酰胺中的荧光性质。在紫外光激发下，这些配合物表现出铕离子和铽离子的特征荧光。讨论了影响荧光强度的溶剂因素。
