摘　　要：以苯丙氨酸和VB6为原料,合成VB6缩苯丙氨酸希夫碱配体及其钆配合物,用红外光谱、紫外光谱和荧光光谱对希夫碱和配合物进行表征,并进行抑菌活性试验。结果表明,VB6缩苯丙氨酸希夫碱及其钆配合物具有较强的荧光和抑菌活性,并且配合物的荧光主要是配体发光而不是钆的发光。The schiff base ligand VB6-phenylalanine was prepared by the condensation reaction of VB6 with phenylalanine, and its gadolinium complex was further synthesized. The ligand and its complex were analyzed and characterized by IR, UV-vis and fluorescent spectroscopy. Their antimicrobial activities were investigated. The results showed that the ligand and its gadolinium complex had strong fluorescent emission and antimicrobial activities. The fluorescent of complex may be assigned to intraligand emission.
