| titleOfInvention | Fluorescent probe with chalcone structure, preparation method thereof and application of fluorescent probe in hydrazine detection |
| abstract | The invention provides a method for preparing a compound based on chalconeA fluorescent probe with a structure, a preparation method and application thereof in hydrazine detection. The probe is 3- (3 ' - (2 ' -chloro-7 ' - (diethylamino) quinolyl) allyl acetonyl) -7-diethylamino coumarin (QCT-Cl). The probe QCT-Cl is prepared by taking 2-chloro-7-diethylamino quinoline formaldehyde and 7-diethylamino coumarin-3-ethanone as raw materials through a condensation reaction, and is mild in synthesis conditions and simple in purification. The QCT-Cl is a fluorescence enhanced fluorescent probe, after hydrazine acts with the fluorescence enhanced fluorescent probe, the solution of the hydrazine is changed from weak red to bright blue under an ultraviolet lamp by naked eyes, the selectivity is high, the anti-interference performance is strong, the sensitivity is high, and the minimum detection limit for detecting the hydrazine is 9.46 multiplied by 10 ‑8 mol/L, can be used as a fluorescent probe for qualitatively and quantitatively detecting hydrazine, and is widely applied to the detection of hydrazine in the environmental and biological fields. |
