| Abstract: | A fluorescent chemosensor,2-hydroxy-1-naphthaldehyde1-amino-hydantoin（L）,was designed and synthesized.L was investigated to recognize metal ions by its absorption and fluorescence spectra.L showed a high selective response to Mg2＋.In acetonitrile,Mg2＋ induced a huge enhancement in the fluorescence intensity of L by 30 folds with maximal emission wavelength of 448nm.The stoichiometric ratio between L and Mg2＋ was 2：1 based on Job’s plot.The binding mode and Mechanism of fluorescence enhancement of L with Mg2＋ were briefly discussed. |
