“…Two Schiff base fluorescent chemosensors containing thiazole derivatives were synthesized by the condensation reaction between 2‐hydroxy‐5‐(4‐oxo‐3‐phenyl thiazolidin‐2‐yl) benzaldehyde and 2‐aminophenol for one of the probes ( L72 ) and 5,5′‐(4‐oxothiazolidine‐2,3‐diyl)bis(2‐hydroxy benzaldehyde) and 2‐aminophenol for the second one ( L73 ) [148] . Both presented selectivity towards Al 3+ over other metal ions with limit of detection (LOD) values of 0.11 μM and 4.4 μM respectively.…”

“… It is known that the ESIPT process leads to a decrease in fluorescence . Generally speaking, as a typical Lewis stearic acid, Al 3+ ions are more likely to complex with N- and O-atom donor sites. ,, Therefore, the coordination of Al 3+ and an uncoordinated hydroxyl group of UiO-(OH) 2 @RhB destroyed the intramolecular hydrogen bond (OH···O) and resulted in deprotonation of the phenolic hydroxyl groups, thereby inhibiting the ESIPT process. , The blue shift of the fluorescence spectra at λ em = 500 nm demonstrated the deprotonation.…”

In this work, a novel zirconium-based metal–organic framework (MOF) composite material, UiO-(OH)2@RhB, has been solvothermally prepared with zirconyl chloride octahydrate, 2,5-dihydroxyterephthalic acid, and rhodamine B (RhB) for ratiometric fluorescence sensing of Al3+ ions in an aqueous medium. The luminescence measurement results showed that, at the single excitation wavelength of 420 nm, the fluorescence intensity of the ligand at 500 nm increased significantly in the case of Al3+, while that of RhB at 583 nm changed slightly, together with an apparent color change. Under optimal conditions, UiO-(OH)2@RhB exhibited an extraordinary sensitivity (10 nM), good selectivity, and a fast response (2 min) for Al3+. As far as we know, the limit of detection is superior to that of the current reported MOF-based Al3+ fluorescence sensors. The response mechanism suggested that −OH could capture Al3+ in water through coordination and high electrostatic affinity and achieved turn-on ratiometric fluorescence through the excited-state intramolecular proton transfer process and stable fluorescence of RhB. In addition, this sensor was also applied to actual food samples (grain beans), with the recoveries ranging from 89.08% to 113.61%. Such a turn-on ratiometric fluorescence sensor will provide a constructive strategy for the ultrasensitive detection of Al3+ in practical applications.

This study presents a comprehensive analysis of the synthesis and photophysical properties of thiazolidine-functionalized chiral ionic liquids (CILs) derived from L-cysteine. The synthesis involves a four-step route, encompassing N-protection, coupling reactions with bromoalcohols, and ionic liquid formation. The optical properties of the compounds were evaluated using UV–Vis absorption and fluorescence emission spectroscopies, revealing distinct behavior for different heterocycles and counter-ions. Notably, the investigation reveals that thiazolidine-based CILs exhibit unconventional intrinsic luminescence characteristics. Building upon these photophysical properties, an interaction study was conducted between copper (II) and the CILs. The findings exhibit a robust linear relationship between the optical response and the concentration of the metal ion. Through the calculation of the Stern–Volmer quenching constant, it was determined that the 1:1 binding model is applicable. This research underscores the potential of UV–Vis absorption spectroscopy as a highly sensitive method for detecting metal ions. By elucidating the synthesis, photophysical behavior, and metal ion interaction of thiazolidine-based CILs, this study contributes valuable insights into the field of functionalized ionic liquids and their potential applications in various areas.
