摘要：
A simple cleft-shaped anion receptor 1 containing amide and hydroxyl as recognition units was synthesized and its anion recognition properties were investigated by naked-eye observation, UV-vis, fluorescence and (1)H NMR spectra. Receptor 1 could effectively recognize F(-) via multiple H-bonding interactions, along with visible color change and remarkable fluorescence enhancement. interestingly, reference compound 2 only containing amide groups did not display any interaction for all of the examined anions, including F(-).
