“…However, overexposure to F − can cause diseases, including dental fluorosis, skeletal fluorosis, kidney dysfunction, and even cancers. 2,3 The double-side effects of F − ions make it imperative to develop simple, efficient, and real-time methods for detecting F − ions. Conventional techniques for F − detection include ion-selective electrodes, chromatography−mass spectrometry, ion chromatography, and so forth.…”

“…For example, F – can improve mineral deposition in bones and prevent dental caries by interacting with hydroxyapatite on the surface of teeth to form a protective layer. However, overexposure to F – can cause diseases, including dental fluorosis, skeletal fluorosis, kidney dysfunction, and even cancers. , The double-side effects of F – ions make it imperative to develop simple, efficient, and real-time methods for detecting F – ions. Conventional techniques for F – detection include ion-selective electrodes, chromatography–mass spectrometry, ion chromatography, and so forth. − However, these methods have shortcomings such as high cost, complex operation, and inconvenient transportation, thereby limiting their application in detecting F – , especially in regions lacking professional supervision.…”

Excessive content of fluoride ions (F − ) in water will lead to water pollution and endanger human health, so the research on the method of low-cost, rapid, and efficient detection of F − is of particular significance. In this work, an amino-functionalized ligand with an appropriate triplet energy excited state, 2′-amino-[1,1′:4′,1″-terphenyl]-3,3″,5,5″-tetracarboxylic acid (H 4 TPTC-NH 2 ), was selected to construct a luminescent single-lanthanide metal−organic framework, EuTPTC-NH 2 , with uncoordinated amino groups for the detection of F − . Based on host−guest interactions, that is, hydrogen bonds formed between the free amino groups and F − ions, EuTPTC-NH 2 was developed as a ratiometric fluorescence probe for F − detection with good antiinterference ability, low detection limit, high water stability, and selectivity. It was found that EuTPTC-NH 2 has an excellent linear response to F − in the concentration range of 0−80 μM with high sensitivity and a low detection limit of 11.26 μM. A hydrogel membrane based on the combination of EuTPTC-NH 2 and agarose was also prepared for the quantitative visual detection of F − in water.

“…Compared with DPTPE, the NÀ H group in DPCN was more easily deprotonated, because the introduction of the strong electron-withdrawing cyano group helped the deprotonation of NÀ H group F À . [2] Therefore, DPCN exhibited a better detection effect for F À .…”

Two novel benzothiadiazole derivatives were prepared. Clear color changes from orange‐red to blue (DPCN) and pink to green (DPTPE) were observed after the addition of fluoride ions (F−). DPCN and DPTPE displayed ratiometric fluorescence changes in the presence of F−. 1H‐NMR titration and DFT calculations confirmed deprotonation in the presence of F−. Compared with DPTPE, the hydrogen proton of the imine group in DPCN had higher activity due to the influence of the strong electron‐withdrawing cyano group, such that it was more easily deprotonated and the detection limit for F− was much lower. This work provided guidance for the further design and preparation benzothiadiazole based colorimetric and ratiometric fluorescence sensor for F−.
