摘　　要：A simple colorimetric acetate ion receptor based on 3-methoxysalicylaldehyde-4＇-nitrophenyl-hydrazone was synthesized in an ethanol solution through one step,and characterized by 1H NMR and elemental analyses.Its anion-binding ability was examined by UV-Vis absorption spectroscopy in DMSO（dimethyl sulfoxide）.The result shows that the compound has a high affinity for and a high selectivity toward acetate ions,and also an advantage of ＇naked-eye＇ recognition of color changing from yellow to purple.A simple colorimetric acetate ion receptor based on 3-methoxysalicylaldehyde-4＇-nitrophenyl-hydrazone was synthesized in an ethanol solution through one step,and characterized by 1H NMR and elemental analyses.Its anion-binding ability was examined by UV-Vis absorption spectroscopy in DMSO（dimethyl sulfoxide）.The result shows that the compound has a high affinity for and a high selectivity toward acetate ions,and also an advantage of ＇naked-eye＇ recognition of color changing from yellow to purple.
