摘要：

A new 4-aminoantipyrine -based Schiff-base (M) was synthesized. Its structure was characterized by using IR, 1H NMR and elemental analysis. The influences of a number of different metal ions on its UV-Vis absorption and fluorescence spectral were studied in acetonitrile. Spectroscopic studies revealed that compound M could detect Cu2+ by UV-Vis absorption and fluorescence spectrophotometry. The stoichiometry ratio of M-Cu2+ was 1:1, respectively. Moreover, the detection limit was calculated to be 1.41 μmol/L for Cu2+ ion. The analysis suggested that M could behave as a fluorescent sensor for the selective detection of Cu2+ and the binding constant was 6.5×104 L/mol. Thus a new kind of chemosensor for Cu2+ with high sensitivity and selectivity was introduced.
