A Fluorescent Probe for Sensitive Detection of Hydrazine and Its Application in Red Wine and Water

抄録

A fluorescent probe, 7-(diethylamino)-2-oxo-2H-chromene-4-carbaldehyde (probe 1), was designed and synthesized for the sensitive detection of hydrazine. The addition of N₂H₄ caused the fluorescence intensity of probe 1 to decrease. The probe’s fluorescence was turn-off after adding N₂H₄, which could be observed under UV light at 365 nm. Moreover, once treated with different concentrations N₂H₄ solutions, the solution color change could be distinguished, which indicates that probe 1 could be used as a visual sensor for hydrazine. Moreover, probe 1 can be used as a signal tool to determine hydrazine levels in solutions, such as red wine and water.
