چکیده انگلیسی
Recently, growing attention has been paid to the selective and sensitive detection of hypochlorite anion (ClOâ) because of its important roles in biological systems. Although great progress has been made in fluorescent probe for tracking of ClOâ in living cells to figure out its biological function and pathogenic mechanism, simple and convenient tools for the detection and determination of ClOâ in water and other ClOâ used field are rarely exploited. In this article, we developed a simple water-soluble tricyanoethylene-derived colorimetric probe 1 for the fast and sensitive detection of ClOâ in absolute aqueous solution by the naked-eye. Probe 1 exhibited an excellent selectivity toward ClOâ for the strong oxidative property of ClOâ to the strong electron deficient CC bond. Additionally, probe 1 could detect ClOâ quantitatively in the range of 0-120 μM with the detection limit of 4 μM. We highlight the simplicity of the design and synthesis, yet its combined properties, such as high specificity, excellent sensitivity, good water-solubility, fast response, higher molar extinction coefficient, and visual determination, and anticipate that this probe would be of great benefit to analytical researchers for monitoring the ClOâ levels in the environment.
