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.
