Abstract
The fluorescence-enhanced probe was synthesized based on 4-aminoantipyrine and 2-hydroxy-1-naphthalaldehyde. The structure was characterized by NMR, ESI-MS, IR and X-ray single-crystal diffraction. The fluorescent probe HL1 synthesized in this thesis have recognition performance for Hg2+ and Ag+ in acetonitrile solution, with HL1 allowing visual detection of Hg2+. Their recognition properties and mechanisms were examined and investigated using fluorescence spectroscopy and ESI-MS. The binding ratios between the probe and the response ions were 1:1, while the detection limits for the response ions both reached 10–8 M and below, with the potential to detect actual samples.
