“…Hence, it is of the utmost importance to develop a highly sensitive tool for the detection of mercury and its compounds. To date, various analytical techniques and detection methods have been established for Hg 2+ , each with their advantages and limitations. , However, our innovative approach introduces an atomically precise structural architecture into this application. This not only enhances the efficacy of detection but also enables us to detect even the lowest possible concentrations of Hg 2+ in water.…”

We outline an approach for the first time to employ a Ag(I) cluster-assembled material as a surface-enhanced Raman scattering (SERS) sensor for the detection of Hg 2+ ions. Our research focuses on the design of [Ag 12 (S t Bu) 6 (CF 3 COO) 6 (TPSBF) 6 ] n (TUS 4) (TPSBF = 2,2′,7,7′-tetra(pyridin-4-yl)-9,9′-spirobi(fluorene)), which is constructed by stitching Ag 12 cluster nodes in a three-dimensional manner using tetradentate spirobifluorene linkers. The structural arrangement of TUS 4 plays a crucial role in its optical characteristics, distinguishing it from grind samples and ensuring its suitability in its crystalline state. Credited with its exceptional chemical stability within the intricate structural architecture, TUS 4 is utilized as a sensing probe in SERS for precise detection of Hg 2+ ions under controlled conditions. Due to its atomic specificity and distinctive structural architecture, TUS 4 attains an unprecedentedly low detection limit, 0.07 pg mL −1 , achieved through the formation of the Ag−Hg amalgam.

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.
