Rhodamine Schiff bases as fluorescent chemo-sensors, fluorogenic cation sensors, is scientifically exigent work. base derivatives have gained attention due to their structural variability. The combination of donor and acceptor groups with delocalized π-orbital results in excellent properties intramolecular charge transfer (ICT) opening spirolactam ring moiety. In this review, we summarize information about sensors reported over the past two decades (2002–2022). We focused on design, synthesis, sensing mechanism (ON/OFF, OFF/ON, ON-OFF-OFF) these for Fe3+ Cu2+ metal ions, well practical applications. also examined how photophysical change when they coordinate resulting changes typical behaviour, such a hypochromic/hyperchromic or hypsochromic/bathochromic shift. anticipate that review will provide fundamental framework researchers further investigate Schiff-based sensors.

ABSTRACT A new hybrid inorganic–organic probe, phenylphosphonothioic salicylic dihydrazone (PPSD), was designed, synthesized, and characterized as Schiff base via simple condensation reaction using two units of salicylaldehyde with dihydrazide (PPDH). In the colorimetric studies, PPSD in methanol medium responded probe to detect cations iron (Fe 2+ ) zinc (Zn ). During attempts venture series , Co Ni Ca Li + Zn Cu Na Al 3+ Ce ), detection observed specifically Fe cations. Herein, colorless identified turn into dark blue cations, whereas showed fluorescent green under UV light. To validate these detections, were studied by UV‐vis photoluminescence. absorbance analysis performed for while found be supported photoluminescence data. Based on fluorescence titration limits (limit [LOD]) (9.7789 × 10 −5 M) (9.6340 established, respectively. The binding constants determined 7.92 4 M −1 2.76 8 from Benesi–Hildebrand (B‐H) equation. Consequently, a quantum yield (ɸ = 0.038), which increased approximately 11‐fold 0.417) due its interaction FTIR, multinuclear NMR ( 1 H, 13 C, 31 P), photoluminescence, UV‐vis, titration, HRSEM, EDS, cyclic voltammetry, DFT studies used characterize structures, sensing abilities /Zn
