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).
