“…Besides, the limit of detection (LOD) values of water in the different solvent were calculated by using equation detection limit=3S/k, where S is the standard deviation of the blank measurement and k is the slope between the fluorescence intensity versus V/V % of water. The LOD values obtained were in the range of 0.003–1.5 V/V% (Table S1, Figure S17) for different solvent pairs where water is one of the essential components among the solvent pair and it is comparable to the previous reports [47,48] . Along with that the selectivity of the HL1 probe towards water has been determined in a mixture of two solvent combinations through fluorescence spectroscopy.…”

The results indicated that the HL1 probe selectively senses water by turning off the emission over other solvents (Figure S18).…”

Designing fluorescent probes and its metal‐organic materials getting attention due to their fascinating utility in several fields from material to biology. Here, we synthesized N‐phenyl glycine substituted four new fluorescent probes viz. (2‐cyanophenyl)glycine [HL1], (5‐chloro‐2‐cyanophenyl)glycine [HL2], (4‐chloro‐2‐cyanophenyl)glycine [HL3], (2‐cyano‐3‐fluorophenyl)glycine [HL4] and investigated its properties through spectroscopic techniques. Out of all probes, HL1 displayed non‐emissive nature in the presence of water and uniquely detect the percentage of methanol in the methanol‐water mixture or vice‐versa out of the different solvent‐water mixture with the help of fluorometric technique. Furthermore, cobalt complex [Co(L1)(phen)2]ClO4 (C1) with distorted octahedral geometry has been synthesized by using HL1. The emissive nature of the complex C1 was further utilized for the selective sensing of S2− ion in the DMSO‐water mixture by quenching the fluorescence with a detection limit of 4.8 μM. The selective solvent percentage detection and anion sensing illustrate the potential efficacy of the designed sensors for analytical intent.

“…It is considered as a gold standard for water content measurements according to multiple publications. [13][14][15][16] ASTM International (ASTM) also published a standard test method for water in organic liquids by coulometric KF. 17 However, it is a destructive technique, requires a specic reagent, and takes considerable time for one measurement.…”

J‐aggregation and H‐aggregation are identified as two classical models of functionally oriented non‐covalent interactions, and significant attention has been drawn by researchers. However, due to the scarcity of single‐crystal examples of H‐aggregation, a comprehensive understanding of the relationship between its stacking mode and optical behaviour has been hindered. In recent studies, two polyaromatic Schiff base compounds, Cl‐Salmphen and H‐Salmphen, were successfully synthesized, and both were found to exhibit H‐aggregation. In the findings, H‐Salmphen was shown to display typical C─H···π interactions, characteristic of Aggregation‐Induced Emission (AIE) active molecules, whereas its halogenated counterpart was identified as behaving similar to Aggregation‐Caused Quenching (ACQ) active molecules. These types of results suggest that identical intermolecular interactions can produce differing optical behaviours. Light was shed, at least in part, on the formation mechanisms of H‐type aggregates and their luminescence properties from these observations. Additionally, the high optical signal‐to‐noise ratio inherent to H‐aggregates was utilized for the exploration of water content detection. As an outcome, a high‐performance fluorescent filter paper was developed, enabling easy real‐time detection using a smartphone.
