A new highly sensitive colorimetric receptor 1 for fluoride based on anthracene-9,10-dicarbaldehyde bis-p-nitrophenylhydrazone was designed, synthesized and characterized. Experiments showed that the receptor 1 can selectively recognize the fluoride in DMSO and even in 95/5 DMSO/H(2)O (v/v) mixtures. The ability of recognition and the bond between receptor 1 and anions were determined using visual inspection, UV-vis and fluorescence analyses. In addition, (1)H NMR experiments were carried out to explore the nature of interaction between receptor 1 and fluoride. Finally, analytical application and detection of fluoride in toothpaste have been studied.
基于蒽-9,10-二醛双对硝基苯腙，设计、合成并表征了一种对氟离子具有高灵敏度的新型比色受体 1。实验表明，受体 1 可以在 DMSO 中，甚至在 95/5 DMSO/H(2)O（v/v）混合物中选择性识别氟离子。通过目视检查、紫外可见光谱和荧光分析来确定识别能力和受体 1 与阴离子之间的键合。此外，还进行了 (1)H NMR 实验，以探究受体 1 与氟离子之间的相互作用性质。最后，研究了该受体在牙膏中氟离子的分析应用和检测。
