Hydrazine (NH) is a crucial chemical raw material extensively utilized in chemical production. However, due to its volatility, water solubility, and high toxicity, both the gaseous form and aqueous solution of NH pose significant environmental risks by causing severe pollution that can adversely impact plants, microorganisms, and human health. Therefore, accurate detection of NH in the environment is imperative for safeguarding public health. In this study, we synthesized a ratiometric fluorescent probe (BCaz-Cy2) based on Carbazole and Hemicyanine groups. This probe exhibits simple synthesis procedure, rapid response time, high sensitivity and selectivity as well as remarkable detection signals. It enables effective detection of NH in various matrices such as water, food, soil and plant samples thereby significantly expanding the scope of applications for NH probes.
联氨（NH）是一种重要的化学原料，广泛应用于化工生产中。然而，由于其挥发性、水溶性和高毒性，NH 的气体形式和水溶液都会造成严重的环境污染，对植物、微生物和人类健康造成负面影响。因此，准确检测环境中的 NH 对于保障公众健康至关重要。在本研究中，我们合成了一种基于咔唑和半花菁基团的比率荧光探针（BCaz-Cy2）。该探针具有合成步骤简单、响应速度快、灵敏度和选择性高以及显著的检测信号等优点。它能够有效地检测水、食品、土壤和植物样品等各种基质中的 NH，从而显著扩展了 NH 探针的应用范围。
