A bis-hydrazone Schiff base chemosensor for highly selective and sensitive colorimetric and fluorometric detection of nitrite for environmental, biological, and food sample applications

A novel symmetrical bis-hydrazone Schiff-base probe, 2,2′-((1E,1′E)-((1,2-diphenylethane-1,2-diylidene)bis(hydrazine-2,1-diylidene))bis(methaneylylidene))bis(4-nitrophenol) (L), was successfully synthesized and comprehensively characterized using FTIR and NMR spectroscopy, ESI-MS, elemental analysis, and density functi...

New Coumarin-Schiff Bases: Synthesis, Electrochemical Behavior, Anion/Cation Sensing Capacities, Spectroscopic Analysis, DFT Studies and NLO Properties

A water-soluble pyrazinium-based chemosensor for TNP detection: applications in MCF-7 cancer cell imaging and fingerprint visualization

Density functional theory calculations were performed to support the experimental findings by elucidating the ground-state electronic structure and transitions, with particular emphasis on interactions between the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO).

Design and Synthesis of Dual Fluorophore for Detection of Fe3+ and Hg2+ in Aqueous Solution Through Fluorescence "Turn-Off".

Here, we report the design and synthesis of a new bicyclic compound 6, annulated with benzene and the 8-hydroxyquinoline fluorophore. The probe exhibits a moderate aggregation-induced emission (AIE) behavior upon the addition of water up to 17%. Furthermore, the probe exhibits a highly selective fluorescence turn-off r...

Cyanide-Triggered Fluorescence Turn-On in an Indole-Based Chemodosimeter

A Transition Metal Schiff Base Coordination Compound as a Chemosensor for Sensitive Detection of 2,4,6-Trinitrophenol

In this study, a Schiff base-derived Pd(II) complex (L–Pd) was successfully synthesized and investigated as a fluorescent sensor for the detection of 2,4,6-trinitrophenol (TNP), a highly hazardous nitroaromatic explosive pollutant. Fluorescence studies demonstrated that the L–Pd complex exhibits strong emission propert...
