Hydrazine possesses a diverse range of applications and exhibits favorable water solubility, which can lead to contamination and toxicity in both the natural environment and human beings due to improper handling. Therefore, it is particularly important to establish a reliable and accurate analytical method for detecting hydrazine. In this study, we designed and synthesized a flavonoid-based fluorescent probe DP-N2H4 that specifically tailored for hydrazine detection, thoroughly investigating its spectral properties and response mechanism. DP-N2H4 demonstrated exceptional selectivity towards N2H4 with an impressively low detection limit of 0.468 μM, showcasing remarkable sensitivity towards N2H4 as well. Furthermore, our findings demonstrated that the probe effectively recognized hydrazine in various environmental and biological samples including ambient water, soil, and living cells.
