| titleOfInvention | A ratio probe for detecting mercury ions and its preparation method and application |
| abstract | The invention relates to a ratio probe for detecting mercury ions, a preparation method and application thereof. Specifically, the present invention provides a probe for detecting mercury ions with simple operation and high sensitivity. The probe name is 7-diethylamino-3-(3-(7-diethylamino)coumarinyl)-3-oxopropenylquinoline-2-ketone, referred to as QCT-O. QCT-O is obtained by reacting 7-diethylamino-2-oxo-1,2-dihydroquinoline-3-formaldehyde and 7-diethylaminocoumarin-3-ethanone as raw materials under the action of a catalyst . The probe has rapid response, strong selectivity and high sensitivity to mercury ions. In the presence of mercury ions, the color of the probe solution changes from red to yellow (under sunlight), and from red fluorescence to blue-green fluorescence (under UV light); and the absorption peak at 500 nm disappears, and new ones appear at 380 nm and 440 nm. At the wavelength of 650 nm, the fluorescence intensity changed significantly, and the absorption and emission response intensity changed linearly with the mercury ion concentration, and the minimum detection limits were 2.62×10 ‑8 mol/L and 4.37×10 ‑8 mol /L. |
