ABSTRACT Many industries use copper metal ions (Cu 2+ ions), and their salts are utilized as supplemental materials in both agriculture medicine. Identifying monitoring these Cu biological environmental specimens is crucial due to association with several health issues. In this investigation, we have designed a simple quinoline‐based receptor ( E )‐3‐(((2,4‐di‐tert‐butyl‐5‐hydroxyphenyl)imino)methyl)‐6‐methoxyquinolin‐2(1H)‐one QAP ) containing imine functional groups inspect its capability identify semi‐aqueous medium. The photophysical characteristics structural confirmation of the were investigated using various spectroscopic techniques. Among ions, displayed an intense color shift from slightly yellow strong existence visualized by nude eye. Furthermore, fluorescence spectral maximum wavelength at 485 nm cyan quenched upon introducing ions. alteration colorimetric features coordination complex formation. present sensor shows linear range 3 69 μM, subsequent computed limit detection 3.16 nM, which much lower than that threshold drinking water set WHO. Therefore, can respond sensing two ways: changing quenching fluorescence. binding mode 1:1 stoichiometry, according ESI‐mass, Job's plot analysis, density theory (DFT) computations. practical utility fluorescent was applied for determination samples (drinking, tap, dam water) cancer cells (HeLa cells).

Ratiometric lanthanide coordination polymers (Ln-CPs) are advanced materials that combine the unique optical properties of ions (e.g., Eu3+, Tb3+, Ce3+) with structural flexibility and tunability polymers. These widely used in biological chemical sensing, environmental monitoring, medical diagnostics due to their narrow-band emission, long fluorescence lifetimes, excellent resistance photobleaching. This review focuses on composition, sensing mechanisms, applications ratiometric Ln-CPs. The mechanism relies two distinct emission bands, which provides a self-calibrating, reliable, precise method for detection. relative intensity ratio between these bands varies concentration target analyte, enabling real-time monitoring minimizing interference. approach is particularly suitable detecting trace analytes use complex environments where factors like background noise, temperature fluctuations, light variations may affect results. Finally, we outline future research directions improving design synthesis Ln-CPs, such as incorporating long-lifetime reference luminescent molecules, exploring near-infrared systems, developing up-conversion or two-photon materials. Progress areas could significantly broaden scope Ln-CP applications, especially biosensing, other fields.
