Abstract

A new fluorescent chemosensor based on an acyclic tetra-sulfonamide derivative linked to two dansyl groups has been conveniently synthesized. Its high selective binding ability to fluoride ions over other halide ions was demonstrated by using fluorescence as well as 1H NMR spectra.

A new fluorescent chemosensor based on a tetra-sulfonamide derivative was synthesized, which displayed high selective fluorescent effects on the fluoride ion over other halides.

  • A naked-eye visible colorimetric and ratiometric chemosensor based on Schiff base for fluoride anion detection

    2021, Journal of Molecular Structure
    Citation Excerpt :

    Colorimetric sensors detection is dependent on the color variation of the analytes observed by naked eyes, where guests and colorimetric sensors are bound together with different forces. There are many structures used to build colorimetric sensors, such as anthracene, naphthalene, indole, dansyl and imidazole, etc [24–29]. The advantages of colorimetric sensors are fast response, high sensitivity, good selectivity, simple operation and data analyses, reasonable price and intuitive color changes by naked eyes [30].

    Citation Excerpt :

    Along with several rigid dipodal bissulfonamide anion receptors 70–86 discussed in this section, an acyclic tetrasulfonamide receptor 87 derived from rigid dipodal spacer was also reported by Chen et al. long time ago. The fluorescent chemosensor 87 linked with two dansyl groups exhibited high binding selectivity towards fluoride over other halide anions, as observed from fluorescence and 1H NMR binding studies [76]. The secondary squaramide based rigid scaffolds (Scheme 3) with different substituents are another different class of dipodal anion receptor frameworks known in literature other than bisamides and bissulfonamides.

    Citation Excerpt :

    Colorimetric sensing methods are one of the most effective and selective methods for the detection of many guests such as anions, cations and organic compounds [1–13]. Various colorimetric sensors such as anthracene [14], dansyl [15], imidazole [16], anthraquinone [17] and indole [18] were designed to obtain their best structure for guest binding. The advantages of this method over other techniques are high sensitivity, simplicity, fast response, analysis in both quality and quantity, analysis using simple instruments and easily observed by color changes in the presence of target guests [19].

  • Highly selective colorimetric and fluorescent chemosensor for fluoride based on fluorenone armed calix[4]arene

    2017, Sensors and Actuators, B: Chemical
    Citation Excerpt :

    Calix[4]arenes are found to be very attractive receptors because they are building blocks which can be readily modified at the both upper and lower rims and also they have flexible conformation for recognition of guest molecules [28–33]. Modified calix[4]arene in upper and lower rim with functional groups such as amide [10,13,32,34–43], pyrrol [44–55], imidazolium [56–63], urea and thiourea [64–66], which have bonded to fluorogenic groups like naphtyl, antranyl, pyrene, etc, are used widely for detection of divers range of anions and molecules [28–33,56–63]. Diverse mechanisms such as photoinduced electron transfer (PET) [67,68], metal-ligand charge transfer (MLCT) [69], proton transfer [19], formation of an excimer [19,70,71] and intramolecular charge transfer (ICT) [72,73] were proposed for signal transduction of calix[4]arene-based fluorescent chemosensors.
