A novel chemosensor (HNTS) has been designed for a fast and accurate detection of F in acetonitrile medium. The UV-Vis, H, C NMR experiments and computational calculations demonstrate that HNTS probe offers a potential colorimetric sensor for discriminating F among other relevant anions. The detection limit is as low as 6 μM and a reversible colorimetric switch could be devised by sequential addition of F/Ca. The promising application of HNTS is also confirmed in real examples where the concentration of F is a critical parameter, e.g., commercial toothpaste, paper strip and gel form analysis of samples.
一种新型化学传感器（HNTS）已被设计用于在乙腈介质中快速、准确地检测 F。紫外-可见、氢、碳核磁共振实验和计算计算表明，HNTS 探针提供了一种潜在的比色传感器，可用于区分 F 与其他相关阴离子。检测限低至 6 μM，通过顺序添加 F/Ca 可以设计出可逆的比色开关。HNTS 的有前途的应用也在实际例子中得到了证实，其中 F 的浓度是一个关键参数，例如商业牙膏、纸条和凝胶形式的样品分析。
