A Highly Selective and Colorimetric Fluorescent Probe for Hydrazine Detection in Water Samples.

A new highly selective and visible colorimetric fluorescent probe (probe 1) was developed to detect hydrazine (N2H4) concentration in real water samples. As different concentrations of N2H4 were added, the color of the probe solution was graded gradually from colorless to pink, which could be observed by the naked eye under UV light at 365 nm. Our research indicates that probe 1 offers a certain practical significance for use as a visible detection agent to detect N2H4 efficiently by distinct color response. Furthermore, our work showed that probe 1 can be successfully applied to detect N2H4 concentrations in real water samples.
