A solvent-dependent dual chemosensor for detecting Zn2+ and Hg2+ based on thiophene and thiourea functional groups by fluorescence turn-on

Stable Two-Fold Interpenetrated Cd(II)-MOF for Selective Dye Adsorption and Luminescence Detection of Hydroxyl-Substituted Nitroaromatic Compounds

“…As is already known, the thiophene ring, which is a five-membered heterocycle containing a S atom, is a good candidate in its compound to improve fluorescence signal for the detection studies. 56,57 In addition, amide moieties (−NH− CO) in the detection and adsorption studies are important to reach to low detection limits and high adsorption capacity via hydrogen bonding interactions. 58 In the literature, amidecontaining MOFs have been widely preferred for the luminescence detection of analyte and dye adsorption.…”

“…In this study, the 5,5′-((thiophene-2,5-dicarbonyl)­bis­(azanediyl))­diisophthalic acid (TDBATH 4 ) ligand containing thiophene and amide groups was preferred in the synthesis of Cd­(II)-MOF. As is already known, the thiophene ring, which is a five-membered heterocycle containing a S atom, is a good candidate in its compound to improve fluorescence signal for the detection studies. , In addition, amide moieties (−NH–CO) in the detection and adsorption studies are important to reach to low detection limits and high adsorption capacity via hydrogen bonding interactions . In the literature, amide-containing MOFs have been widely preferred for the luminescence detection of analyte and dye adsorption. ,, Moreover, the linkers containing amide and thiophene rings in the MOF have been used for the detection of metal ions, anions, small molecules, and NACs and degradation of dyes. − Considering the above-mentioned reasons, the water-stable luminescent Cd­(II)-MOF with the anionic skeleton was synthesized and characterized by various techniques.…”

Synthesis, “turn-on” fluorescence signals towards Zn2+ and Hg2+ and monoamine oxidase A inhibitory activity using a molecular docking approach of morpholine analogue Schiff base linked organosilanes

“…To date, fluorescence-based probes have been chosen as the best detector for Zn 2+ and Hg 2+ due to their low cost, quick response and high sensitivity. 19–23…”

“…To date, fluorescence-based probes have been chosen as the best detector for Zn 2+ and Hg 2+ due to their low cost, quick response and high sensitivity. [19][20][21][22][23] Heterocycles are nitrogen, oxygen and sulphur containing compounds widely used in medicinal chemistry due to their biological activity. 24,25 Morpholine is one of the heterocyclic moieties containing both amine and ether functionality that is extensively used as a pharmacophore in clinical areas.…”

Detection of Hg2+ with NBD‐based colorimetric chemosensor: Practical application to water samples and test strips

“…Thus, humans may be exposed to mercury through the skin, cell membrane, and respiratory system. [10][11][12][13][14] It is also concentrated in marine mammalian tissues due to non-biodegradability of mercury, and ingestion of the organisms brings about absorption and accumulation of mercury in the body. [15][16][17][18][19] In particular, it can lead to biological impairment in vital organs, DNA, hormones, and the central nervous system.…”
