Water-soluble ionic liquid as a fluorescent probe towards distinct binding and detection of 2,4,6-trinitrotoluene and 2,4,6-trinitrophenol in aqueous medium

Benzimidazolium ionic liquid tagged phenazine salophen as a bifunctional ‘off–on’ PET based fluorescent sensor for aqueous phase detection of trinitrotoluene and picric acid

“…Meanwhile, the interaction between the fluorescent probes and nitro compounds could occur in the cationic part of the ILs. In the same line, we have recently developed a water-soluble benzimidazolium based IL containing chloride counter anions for distinct binding and detection of TNT and PA. 35 Both TNT and PA could be detected using the reported probe through two different mechanisms, viz. resonance energy transfer and anion exchange.…”

Tuning the photophysical and photo acidic properties of N-methyl-6-oxyquinolonium-based ionic liquid dyes: the role of solvent and substitution effects investigated by a TD-D3-DFT approach

“…They have been used as fluorescent probes for cellular imaging and as sensing materials for detecting metal ions and other analytes in solution. [33][34][35][36][37][38] Fluorescent ILs are important luminescent materials and have aroused extensive interest in recent years owing to their extensive applications in chiral analysis, 39,40 crystal materials, 41 and the sensing of metal ions, [42][43][44] nitroaromatic compounds, 45,46 bio-macromolecules, 47 and radicals. 48,49 A novel anion-functionalized fluorescent IL has been designed and prepared by Che et al, 50 which was capable of capturing sulfur dioxide with high capacity and could also be used as a good colorimetric and fluorescent SO 2 sensor.…”

AIE/AEE tripodal PEGyl-melphalan supramolecules and detection of trinitrophenol in water

“…Fluorescence-based sensing methods stand out among various techniques due to their simplicity, high sensitivity, affordability, straightforward sample preparation, and portability, offering immense potential. 7 Lots of uorescent sensors have been constructed to detect PA. [8][9][10] A donor-acceptor conjugated polymer based on diethylamine phenyl and benzothiadiazole groups was fabricated to detect PA with a K sv constant of 1.8 × 10 3 M −1 . 11 Hyperbranched conjugated polymers (HCPs) were rst synthesized using truxene and diethynylbenzene derivates, which were carried by F127 in water to form highly uorescent HCP micelles.…”
