以1,8-萘酰亚胺为原料设计合成了一种新的铜离子荧光探针M，并对其结构进行了表征。荧光光谱实验表明：在乙腈溶液中，M对Cu2+表现出识别性能，加入Cu2+，其荧光发生明显猝灭，而对Na+、K+、Ag+、Pb2+、Zn2+、Cd2+、Hg2+等离子无明显响应。因此，该荧光探针对Cu2+有较高的选择性和灵敏度。%A new and effective Cu2+fluorescence probe M based on 1,8-Naphthalimide has been synthesized and character⁃ized. M exhibited high selectivity and sensitivity for Cu2+with fluorescent quenching in acetonitrile and the specific response of M to Cu2+was not affected by other metal ions including Na+, K+, Ca2+, Mg2+, Mn2+, Co2+, Ni2+, Cu2+, Cr3+, Ag+, Pb2+, Zn2+, Cd2+, Hg2+, Fe2+and Fe3+.
