The anion recognition property of a naphthalene based receptor (L) was investigated by naked-eye, UV-Vis, fluorescence, (1)H NMR and computational methods. The receptor L showed fluoride selective naked-eye detectable colorimetric and UV-Vis spectral changes over other tested anions due to the formation of hydrogen bonding complex in 1:1 stoichiometry and/or deprotonation between fluoride and the receptor. Interestingly, the fluorescence of L was quenched by fluoride but enhanced by acetate.
通过肉眼观察、紫外可见光谱、荧光光谱、（1）H NMR 和计算方法研究了基于萘的受体（L）的阴离子识别性能。由于氟离子与受体之间形成 1:1 化学计量比的氢键配合物和/或去质子化，受体 L 对氟离子表现出选择性的肉眼可检测比色和紫外可见光谱变化，而对其他测试阴离子则没有变化。有趣的是，氟离子猝灭了 L 的荧光，但乙酸根增强了其荧光。
