摘　　要：The detection of cations has attracted considerable interest because of their importance in various physiological processes. In this study, compound 1 bearing sulfonamidc and morpholine functionalities was synthesized. Its structure was well characterized by NMR spectroscopy and mass spectrometry. UV/vis absorption spectra and fluorescence spectra indicated that it displayed high sensitivity and selectivity for Cu^2＋ and Ag^＋ by switching solvent media. It means that： （1） it showed selective response to Cu2＋ in acetonitrile, （2） whereas it exhibited high selectivity for Ag^＋ in water. The density functional theory calculations were used to clearly explain the different recognition behaviors in different solvent media. This research suggests that compound 1 bearing sulfonamide and morpholine functionalities could act as a multiftmctional chemosensor for monitoring multiple cations by changing solvent media and provides an alternative approach to design novel dual cations chemosensors.The detection of cations has attracted considerable interest because of their importance in various physiological processes.
