Confined construction of CDs@MIL-101 as reusable and turn-on fluorescence sensor for highly sensitive water detection based on adsorption-solvent synergistic mechanism

Ultrafast Visual Detection of a Trace Amount of Water by Highly Efficient Hybrid Manganese Halides

“…The LOD is calculated to be 9.71 ppm, which is superior to the previously reported fluorescence water sensors (Table S13). ,,− Moreover, the water detection properties of halide 1 in other nonproton solvents were also tested, such as tetrachloride (CCl 4 ), cyclohexane (C 6 H 12 ), and methylbenzene (C 6 H 5 CH 3 ) (Figures S23–S25). The results show that halide 1 also features excellent water detection ability in these solvents with low detection limits of 30.0, 10.1, and 17.8 ppm (Figure d).…”

Regulation of the Metal Center in Lanthanide Nanoparticles to Achieve Multifunctional Sensing

“…Thus, it is crucial to develop a quick and simple method for the accurate quantification of trace water in organic solvents, which has attracted great interest. , 3,5-Cl salen could achieve full-range water content detection (0–100%, v/v) in DMF and ethanol, with low LODs of 0.59 and 0.45 vol %, respectively . Carbon dots (CDs) implanted into MIL-101(Cr) cages show highly selective water capture and sensitive fluorescence changes to water . Orange emission carbon dots (o-CDs) show water sensing in organic solvents and with the LOD of 0.0895% .…”

Enhancing the sensitivity of a water stable MOF as a H2S gas sensor by the fabrication of a mixed-matrix membrane

“…Coordination polymers (CPs)/metal–organic frameworks (MOFs) have been at the center of attraction over the last two decades owing to their multi-dimensional applications in gas separation and storage, 25–29 guest inclusion, 30 proton conductivity, 31 sensing, 32–37 magnetism, 38 and catalysis. 39,40 MOFs are considered for these applications given their high thermal, and chemical, stability, large porosity, tunable surface area, and amenability for post-synthetic modifications.…”

“…[13][14][15][16][17] To date, three fundamental strategies are in use for the development of fluorescent H 2 S probes based on their reaction with H 2 S: (a) reductive reaction with H 2 S: reduction of nitro or azide to amine, and reduction of selenoxide to selenide; (b) nucleophilic addition reaction by H 2 S: Michael addition reactions, addition to double bonds, dual nucleophilic reactions and thiolysis reactions; (c) precipitation reactions by H 2 S as Hg 2+ /Cu 2+ / Au 2+ /Ag + sulfides.
