| 摘 要： | 以甘氨酸和苯甲酰氯为原料合成苯甲酰甘氨酸,在超声波的辅助下苯甲酰甘氨酸与醛类缩合得到噁唑酮衍生物4a-4d,并以荧光光谱法研究化合物对Zn2＋、Fe3＋、Cu2＋三种金属离子的识别作用。实验表明,随着金属离子的加入,化合物的荧光光谱均发生不同程度的猝灭现象;化合物4c对Fe3＋的识别作用最优,猝灭常数为1.57×104 L.mol-1,表现出一定的选择性。

| Abstract: | This paper describes the synthesis of benzoylglycine from glycine and benzoyl chloride,the synthesis of oxazolone derivatives 4a-4d from benzoylglycine and aldehyde by ultrasound-assisted condensation and the study of the recognition of oxazolone deriavatives 4a-4d on Zn2+、Fe3+、Cu2+ by fluorescence spectrometry.The results show that metal ions may lead to the quenching of the fluorescence spectrum and that compound 4c exhibit good selective recognition on Fe3+ with the dissociation constant as 1.57×104 L·mol-1. |
