Heavy metal ions are resistant to degradation and pollute a wide range of natural resources found in the environment, such as water. Detecting heavy metals is crucial for monitoring environmental safety and preventing the harmful effects of metal ion exposure. Therefore, this study has focused on Schiff‐base chemosensors, due to their efficacy in detecting metal ions, owing to their simplicity, cost‐effectiveness, rapid photophysical response, greater sensitivity, minimum detection limit, and applicability to the environmental and medical domains. Such chemosensors are crucial for ensuring public health and safety because they offer a feasible and efficient way to monitor concentrations of heavy metals. This review focuses on using spectroscopic chemosensors to detect Pb2+, Cd2+, and Hg2+ ions. The discussion includes the mechanisms and signal change properties of these chemosensors, as well as critical factors such as the limit of detection, binding stoichiometry ratio, association constant, appropriate pH, and structure. The article concludes with key findings and future perspectives, emphasizing the crucial role of metal ion monitoring devices in protecting the environment and human health.

The present invention reports two novel functional compounds, 2-hydroxy-3-naphthaldehyde thiosemicarbazone (2H3NTS) and 2-hydroxy-3-naphthaldehyde semi carbazone (2H3NS) as an excellent uorescent probe which possess anticancer features and are not yet synthesized by any research group.The DFT study reveals signi cantly higher stokes shift (315 nm) for 2H3NS indicating swift relaxation from initial to the emissive state and reduces self-quenching from self-molecular absorption which favours its practical application. Consequently, successive in-vitro activity of 2H3NTS and /2H3NS is studied using molecular docking towards the inhibition capacity of target kinase protein like CDK, primarily responsible for cell growth. As expected, 2H3NS is capable of binding both competitive ATP binding SITE I and non-competitive SITE II which lies below the T-loop, thereby inhibiting the cell growth and differentiation. However, 2H3NTS with polarizable sulphur is incapable of binding at SITE I with selective inhibition posing the ATP site to be well conserved.
