and its complexes with europium and terbium were synthesized. The complexes were characterized by elemental analysis, infrared spectra and conductivity. The europium and terbium ions were found to coordinate to the C=O oxygen atoms and pyridine nitrogen atoms. The fluorescence properties of these complexes in DMF and CH3OH/CHCl3 were studied. Under the excitation of UV light, these complexes exhibit
合成了酰胺基开环冠醚配体及其与euro和ter的配合物。通过元素分析,红外光谱和电导率对配合物进行表征。发现和ter离子与C = O的氧原子和吡啶的氮原子配位。研究了这些络合物在DMF和CH3OH / CHCl3中的荧光性质。在紫外光的激发下,这些络合物表现出characteristic和ter离子的特征荧光。讨论了影响荧光强度的溶剂因素。
