摘　　要：以邻苯二胺和2-羟基-1-萘甲醛为原料,通过席夫碱反应合成了一个铜离子(Cu^(2+))荧光探针L,并采用紫外、红外以及荧光光谱法研究了探针L对Cu^(2+)的识别能力。结果表明,该荧光探针对Cu^(2+)具有单一选择性,可快速有效检测Cu^(2+)。利用Job’s曲线判断出荧光探针L与Cu^(2+)的配比为1∶1。A copper ion fluorescent probe L was synthesized by Schiff base reaction using o-phenylenediamine and 2-hydroxy-1-naphthylaldehyde as raw materials.The recognition ability of the probe for copper ions was studied by ultraviolet spectroscopy,infrared spectroscopy and fluorescence spectroscopy.The experimental results indicated that the fluorescent probe L possesses a single selectivity in acetonitrile and relevant aqueous solution,which is capable of detecting copper ions quickly and effectively.The Job's curve illustrated that the ratio of the fluorescent probe molecule to copper ions is 1:1.
