Abstract
A new Schiff base 2-hydroxy-5-[(2,7-dihydroxy-1-naphthyl)methylideneamino]benzoic acid (HNMB) has been designed and synthesized. HNMB was characterized by Fourier-transform infrared spectroscopy (FTIR), electrospray ionization mass spectrometry (ESI–MS), nuclear magnetic resonance spectrometry (NMR), and single crystal X-ray diffraction. Fluorescence spectra show that HNMB could be used as a “turn-on” probe to detect ClO− ions from other anions in DMSO/H2O (v/v = 1:1) with a fast response time of 10 s and a low detection limit of 3.6 × 10−7 mol/L. Moreover, the probe could work in a wide pH range of 4–10. The detection mechanism was studied by ESI–MS.
