Benzothiazole-quinoline based probe for simultaneous colorimetric detection of CN- and Cu2+ ions, with fluorescence sensing for Cu2+: Mechanistic insights and practical applications in environmental monitoring and cellular analysis.

ABSTRACT: The development and synthesis of notably targeted and colorimetric sensor based on an azomethine compound for the distinct recognition of Cu²⁺ and CN^- ion individually in an aqueous dimethyl formamide solution is performed. In the presence of CN^- and Cu²⁺, the sensor BTZ showed impressive colorimetric changes, going from pale yellow to orange and pale yellow to dark yellow, respectively. In the meantime, FL spectrum (Cu²⁺) and UV-vis spectroscopy (CN^-/Cu²⁺) were used to assess the sensing features. The plausible binding mechanisms of CN^- and Cu²⁺ ions with sensor BTZ have been studied using the ¹H NMR titration, Job's plot and DFT technique. The bathochromic shift produced by the i
