With the development of chemical industry, threat mercury pollution to human health is increasing. Therefore, it necessary develop a low-cost, convenient and efficient Hg2+ detection method. In this study, anthracene-based fluorescent probes AN-2S AN-4S were synthesized by dithioacetal reaction for rapid concentration in water. Through molecular structure design synthesis route optimization, complexity cost probe greatly reduced. had good water solubility, response abilities anti-interference abilities, could specifically detect using “turn-off” or “turn-on” modes within 1 min. The showed wide linear range (0~40 μmol/L) high sensitivity (4.93 × 10−8 mol/L) 99% aqueous solutions, over pH 5~13. mechanism between was determined 1H NMR FT-IR spectra Job’s curves. It proven that react with molar ratio 1:1 1:2. dual-detection mode enabled be used not only accurate quantitative under fluorescence spectrometer, but also qualitative analysis UV flashlight as test strip, showing broad practical application potential.
