合成了一种以酰胺和羟基为识别单元的简单裂缝型阴离子受体1，并通过肉眼观察、紫外-可见光谱、荧光光谱和核磁共振氢谱对其阴离子识别性能进行了研究。受体1可通过多种氢键相互作用有效识别F（-），沿着可见的颜色变化和显著的荧光增强。有趣的是，仅含有酰胺基的参比化合物2对所有检测的阴离子（包括F（-））没有显示出任何相互作用。(C)2009爱思唯尔有限公司版权所有。
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(-).
