Based on a two-step reaction, the chemosensor L effectively recognized Hg<sup>2+</sup>. The interaction between the chemosensor and Hg<sup>2+</sup> was confirmed by ultraviolet–visible spectrophotometry, fluorescence spectroscopy, electrospray ionization–mass spectrometry, Fourier-transform infrared spectroscopy, and frontier molecular orbital calculations. The chemosensor L was also incorporated into test strips and silica gel plates, which demonstrated good selectivity and high sensitivity for Hg<sup>2+</sup>.</p> 2020-02-19 04:43:54 chemosensor Hg2+ rhodamine 6G test strips silica gel plates
