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

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… CONTINUE READING
