“…Therefore, the optical properties should be sensitive to water molecules and variable depending on the water content. Several strategies have been demonstrated to meet the requirement, such as intramolecular charge transfer (ICT), [5][6][7][8][9] excited state intramolecular proton transfer (ESIPT), [9][10][11] photo-induced electron transfer (PET), [12][13][14][15][16][17][18] aggregation-induced emission (AIE), 7,29,30 decoloration of hydrogen-bonding photochromic dyes, 31 and other water-triggered mechanisms. [19][20][21][22][23][24][25][26][27][28] Generally, in each system, there is a specic range of water concentration available for detection; AIE is observed in high water concentrations, 7,29,30 whereas other systems exhibit optical changes in a relatively low concentration range.…”

“…Universal solvent water may cause several characteristic interactions with excited molecules due to its large dielectric constant and proton donating and accepting properties. Hence, the number of fluorescent probes for the detection of trace amounts of water has been developed so far. − However, these systems have drawbacks such as fluorescent turn off, less sensitivity, and slower response time; these features makes it difficult to detect a trace amount of water in the system.…”

Detection of Moisture by Fluorescent OFF-ON Sensor in Organic Solvents and Raw Food Products

Copper complex based on a new class of fluorescence OFF-ON sensor 1.Cu has been reported for the detection of trace amounts of water in various organic solvents such as CHOH, THF, CHCN, and acetone by means of fluorescence emission intensity. The probe is highly responsive to water in THF (DL = 0.003 wt %). The dissociation of copper from probe 1.Cu in the presence of water is responsible for the fluorescence change and it was confirmed by electrospray ionization-mass spectrometry (ESI-MS), proton nuclear magnetic resonance (H-NMR), and fluorescence lifetime studies. Real application of the probe was successfully applied for the detection of moisture content in commercial products such as salt, sugar, wheat, and washing powder.

“…P05 (P03-methyl methacrylate) in chloroform is non-fluorescent under UV light and remains that way when treated with the anions ( Figure S4). In this case, the poly(methyl methacrylate) backbone may be quenching fluorescence, possibly through a process like photoinduced electron transfer (PET) [32][33][34]. P06 (P03-divinylbenzene) was insoluble in all of the solvents tested and as such, screening was performed with solid samples.…”

Polymeric chemosensors are vital sensing tools because of higher sensitivity compared to their monomeric counterparts and tunable mechanical properties. This study focuses on the incorporation of a hydroxyaromatic 1,2,3-triazole sensor, 2-(4-phenyl 1H-1,2,3-triazol-1-yl)phenol (PTP), into polymers. By itself, the triazole has a selective, fluorometric response to the fluoride, acetate, and dihydrogen phosphate anions, and is most responsive to fluoride. Current investigations probe the suitability of various polymeric backbones for the retention and enhancement of the triazole’s sensing capabilities. Backbones derived from acrylic acid, methyl methacrylate, divinylbenzene, and styrene were explored. UV-illumination, Nuclear Magnetic Resonance (NMR) titration, and ultraviolet-visible (UV-Vis) absorption and fluorescence spectroscopy studies are used to investigate the performance of newly synthesized polymers and the derivatives of PTP that serve as the polymers’ precursors. Among the polymers investigated, copolymers with styrene proved best; these systems retained the sensing capabilities and were amenable to tuning for sensitivity.
