摘要:
A novel high-yield Schiff base was designed and synthesized as an anion receptor that specifically select HSO3- anions in aqueous solutions of H2O/DMSO(15:85, volume ratio), which can be detected via colorimetry under direct visualization. The sensor exhibited different results for other anions, such as F-, Cl-, Br-, I-, H2PO4-, AcO-, HSO4- and ClO4-. The changes in the UV-Vis spectra also show the specific recognition of HSO3-, rather than similar anions H2PO4- and HSO4- in the same aqueous solution. The detection limit of HSO3- was 1 x 10(-6) mol/L.
