摘要

A o-hydroxybenzoyl-(N-butyl-4,6-naphthamimide) hydrazone (1) has been synthesized. Compound 1 displayed high selectivity for F^{鈭?/sup> and Cu2+ with UV/vis absorption and fluorescence spectra, respectively. In the presence of F鈭?/sup>, while the absorption peak of 1 showed the red shift, its fluorescent intensity decreased due to deprotonation interaction. In the presence of Cu2+, both the absorption and fluorescence peaks decreased because of the coordination interaction.}
