摘要
A new fluorescent chemosensor based upon 1,8-naphthalimide and 8-hydroxyquinoline was synthesized, and its fluorescent properties in the presence of different metal cations （Hg^2＋, Ag^＋, Zn^2＋, Fe^2＋, Cd^2＋, Pb^2＋, Ca^2＋, Cu^2＋, Mg^2＋, and Ba^2＋） were investigated. It displayed fluorescence quenching with some heavy and transition metal （HTM） ions, and the quenching strongly depended on the nature of HTM ions.
