O-(p-toluene sulfonamide) benzaldehyde derivative fluorescent probe as well as preparation method and application thereof

The invention provides an o (p-toluene sulfonamide) benzaldehyde derivative fluorescent probe as well as a preparation method and application thereof, and belongs to the technical field of fluorescent probes. The o (p-toluene sulfonamide) benzaldehyde derivative fluorescent probe provided by the invention has a structural formula of # imgabs0, and shows relatively high selective recognition performance on hydrazine, green fluorescence is gradually weakened and blue fluorescence is gradually enhanced when hydrazine is added into a probe solution, and a typical ratio fluorescence signal is presented. 本发明提供了一种邻(对甲苯磺酰胺基)苯甲醛衍生物荧光探针及其制备方法和应用，属于荧光探针技术领域。本发明提供的邻(对甲苯磺酰胺基)苯甲醛衍生物荧光探针的结构式为#imgabs0#其对肼表现出较高的选择性识别性能，在探针溶液中加入肼，绿色荧光逐渐减弱，蓝色荧光逐渐增强，呈现典型的比率荧光信号。
