Abstract

The invention discloses a novel fluorescence probe for detecting hydrazine as well as a preparation method and application of the novel fluorescence probe. The probe has a molecular formula: C27H29NO5and has a structure as shown in the specification. The probe has very strong fluorescence and shows a very strong solubilization color rendering phenomenon. The fluorescence probe shows luminous yellow fluorescence in a mixed solution of DMSO and HEPES in the ratio of 4:1, but is turned into blue fluorescence after interacting with hydrazine. The fluorescence probe disclosed by the invention hasexcellent selectivity, relatively high sensitivity and obvious phenomenon when being used for detecting hydrazine, and the effect of identifying hydrazine by using the probe is still not affected whenthe pH value in a detection environment is 3-12. The preparation method of the novel fluorescence probe is simple, and the prepared product is high in yield.

Description

technical field

[0001] The invention relates to a novel fluorescent probe for hydrazine detection, in particular to a method for preparing a hydrazine fluorescent probe of coumarin derivatives and its application to hydrazine recognition in an aqueous system. Background technique

[0002] As an important class of heterocyclic compounds, coumarin derivatives have good physical and biological properties. In recent years, photophysical properties such as high fluorescence quantum yield, large Stokes shift, excellent photostability, and low toxicity of coumarin derivatives have been increasingly studied.

[0003] Hydrazine (N 2 h 4 ) is a fuel widely used in missile and rocket propulsion systems and a reactant in fuel cells. And because of its high alkalinity and reducing properties, hydrazine has been widely used as an industrial chemical. However, hydrazine is highly toxic to humans and animals, and its concentration is too high, it will cause respiratory tract infection, ...
