“…Some of them have focused on a single major fluorophore building block to track different ions. For instance, Mansha et al reviewed coumarin-derived chemosensors, focusing on the sensing approach and efficiency, while Pooja et al discussed their pH limit, detection limit, and binding mode for different ions [23,24]. Choudhury et al discussed polymeric sensors bearing pendant rhodamine units, focusing on how their high-aqueous solubility, improved stability, signal amplification, and easy fabrication into devices make them worth exploring [25].…”

Toxic cations, including heavy metals, pose significant environmental and health risks, necessitating the development of reliable detection methods. This review investigates the techniques and approaches used to strengthen the sensitivity and selectivity of Schiff base fluorescent chemosensors designed specifically to detect toxic and heavy metal cations. The paper explores a range of strategies, including functional group variations, structural modifications, and the integration of nanomaterials or auxiliary receptors, to amplify the efficiency of these chemosensors. By improving selectivity towards targeted cations and achieving heightened sensitivity and detection limits, consequently, these strategies contribute to the advancement of accurate and efficient detection methods while increasing the range of end-use applications. The findings discussed in this review offer valuable insights into the potential of leveraging Schiff base fluorescent chemosensors for the accurate and reliable detection and monitoring of heavy metal cations in various fields, including environmental monitoring, biomedical research, and industrial safety.

Temperature indicators trace (un)desired thermal impacts across their thermal history upon readout at every point of interest via defined irreversible signal changes. Ratiometric luminescent temperature indicators are attractive due to their fast, sensitive, contactless, spatially‐resolved, and self‐referenced readout. However, they have a limited working range as commonly only one specific temperature‐induced physicochemical effect is exploited. Herein, dual‐threshold temperature indicator supraparticles (SPs) are introduced that expand the working range of individual luminescent probes and enhance the extractable information on the thermal history. These SPs derive their functionality from the synergistic interplay of three spectrally distinguishable luminescent species assembled in one multihierarchical, micrometer‐sized particle of hybrid organic‐inorganic nature. This engineered nanostructure enables the stepwise modulation of the physicochemical microenvironment of two incorporated coumarin species at programmable threshold temperatures, resulting in distinct changes in their emission. As these changes are based on dye‐specific mechanisms that are induced in consecutive temperature regimes, the SPs achieve a scarcely reported broad working range (60–200 °C) with temperature‐dependent response times of minutes to seconds. From a broader perspective, the conceptualized SPs pioneer in how multiple individual luminescent probes with different excitation‐emission properties and indicator mechanisms are synergistically united in one advanced indicator system by precise material engineering.

Heavy metal hazardous and enduring characteristics present a noteworthy risk to both human well‐being and the ecosystem. Heavy metal level monitoring requires accurate and dependable detection techniques. This review emphasizes the requirement for sophisticated detection methods that can address the issues like sensitivity, selectivity, accuracy cost, ease of use of heavy metal ion and allow for more accurate and trustworthy monitoring using organic moiety. It offers a thorough overview of cutting‐edge organic moiety‐based heavy metal detection technique. It primarily discusses four different types of substituted core structures, including coumarin, porphyrin, Schiff bases, and terpyridine, along with their mechanisms, methods, detection limits, and appropriate metal bindings. These moieties exhibit strong coordination with heavy metal ions because of their distinct structural characteristics. They produce stable complexes with complicated ligand‐metal interactions that are useful in a variety of applications, including sensing and catalysis. Each probe was chosen based on its propensity or capacity to identify important analytes in practical applications. To increase the effectiveness and productivity of fluorescence sensing, researchers have recently been working to create new fluorescence chemosensors that can identify many ions at once.
