“…Currently, there are mainly two kinds of fluoride ion probes for organic based molecules: desilylation of Si–O/Si–C bonds and deprotonation through the hydrogen bonding . The chemosensors based on fluoride ion‐induced deprotonation are usually sensitive in the micro‐molar scale and could offer ratiometric readout, but may suffer from false positive signals generated from competing anions such as AcO − , H 2 PO 4 − , and OH − –. Moreover, to avoid fluorescence quenching it is necessary to maintain a low concentration for organic dyes, which reduces the sensitivity and prolongs the time of response.…”

Fluoride anion (F−) plays an important and fundamental role in chemical, biological, pathological, and environmental processes. It is highly desired to develop new methods for facial and efficient F− detection. Herein we present the synthesis and characterization of two effective fluoride ion probes and their selective F− sensing by naked‐eye visualization. A N‐heteroannelated anthraquinone derivative, compound I, was prepared by a cyclocondensation reaction of 1,2‐diaminoanthraquinone with 1,6‐bis(triisopropylsilyl)‐hexa‐l,5‐diyne‐3,4‐dione. Compound I was treated with malononitrile in the presence of Lehnert reagent to afford an HCl adduct, compound II, and an aza‐polycyclic aromatic compound III. All three compounds were characterized crystallographically and were studied photochemically. Similarly, 2,3‐diamino‐1,4‐anthraquinone reacted with 1,6‐bis(triisopropylsilyl)‐hexa‐l,5‐diyne‐3,4‐dione to afford compound IV, which reacted with malononitrile in the presence of Lehnert reagent to yield compound V. Compounds III and V are sensitive and selective probes for the detection of F− with significant color changes. The detection by naked eye visualization is rapid and facile, showing both compounds are potential probes for fluoride ion sensing.

“…The selectivity for OH-and F-can be related to basicity of anions, and also the interactions between the host and the anionic guests. Furthermore, literature search showed that the basicity and binding affinities of these anions can change with the polarity of solvent or solvent mixtures like ACN, DMSO, DMSO/H2O and the host [49][50][51]. For example, an association constant for AcO-was found to be 5.11x10 5 M -1 in ACN:H2O/95:5 (8.32x10 6 in this work) medium by Goswami and Chakrabarty using fluorimetric method [1].…”

In this study, a new compound, viz. 4,4-properties of compound 1 and its metal complexes (1-Zn, 1-Ni and 1-Cu) are tested in the presence of various anionic species in acetonitrile media. Fluorescence measurements indicated that, 1-Ni and 1-Cu do not have any selectivity towards various anions except weak interactions. On the other hand 1-Zn shows good response and selectivity toward acetate ion based on fluorescence enhancement. In addition, JOB studies demonstrate that the interaction between 1-Zn and acetate ion were with a ratio of 1:2 and limit of detection (LOD) of 1-Zn was calculated as 4.76x10 -6 M for acetate ion detection. Moreover, 1-Znprovides a certain change in color in the presence of acetate. The results demonstrate that 1-Zn can be utilized for fluorogenic and naked eye detection of acetate anion.
