“…217,218 Due to the similarity in coordination geometries, chelator-based (such as NTA) fluorescent probes may bind multiple transition metals. 219,220 Fluorescent probes with specially designed metal-binding/reacting moiety may be more specific to metal type, 7,221–226 and can be combined with other technologies such as surface-enhanced Raman spectroscopy, 227 or others. These small molecule and quantum dots-based probes are functionally more versatile, and may be used complementary to genetically encoded sensors that are less toxic, more bio-compatible and more accurate in intracellular localisation.…”

“…Most of the reports demonstrated a fluorescence turn-off response due to the paramagnetic nature of Cu 2+ . However, sometimes the turn-off response is not reliable due to the signals from backgrounds [14][15][16][17]. Therefore, designing a highly selective and sensitive fluorescence turn-on probe for the copper ion has become a great and challenging task.…”

The novel pyrene-appended Schiff base probe L with aggregation-induced emissions (AIE) relevant to an increase in water fractions (0–90%) is synthesized and applied in sequentially detecting Cu2+ and CN˗. The pyrene-based probe L firstly induces the excimer formation in the presence of Cu2+. However, the process can be reversed by sequentially adding CN˗, which is demonstrated using the fluorescence “Off-On-Off” response in semi-aqueous media ethanol water (v/v = 7/3) under physiological pH (5 mM HEPES, pH 7.0). The Job’s plot, mass analysis, 1H NMR titrations, and density functional theory (DFT) interrogations confirm the 2:1 stoichiometry of excimer complex L-Cu2+-L*, preferential binding atoms, and CN˗ tuned complex reversibility. Based on the photoluminescence (PL) titration, the association constant of L to Cu2+ is determined as 4.95 × 106 M−1. From standard deviation and linear fittings, the detection limits (LODs) of Cu2+ and CN˗ are estimated as 219 nM and 580 nM, respectively. The practicality of Cu2+ and CN˗ detection is demonstrated using a TLC plate and a blended polymer membrane through which significant color changes under a UV lamp can be monitored. Moreover, utility of the designed probe L towards biological application with low toxicity is demonstrated by detecting Cu2+ and CN˗ inside HeLa cells. The responses of the probe to Cu(II) ions were also verified using living HeLa cells imaging.

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.
