Abstract：
Hydrazine (N2H4), a crucial chemical raw material, enhances people\'s lives and fosters human progress. Hydrazine usage or leakage has caused environmental contamination, affecting water, soil, and living beings. Hydrazine simultaneously presents a possible risk to human health due to its carcinogenic properties. Thus, quick and precise detection of hydrazine is crucial in environmental studies and biological contexts. We prepared a red-emitting fluorescence turn-on probe (XT-HZ) to detect hydrazine specifically. The probe has a low detecting limit for hydrazine (63 nM) with excitation wavelength at 570 nm and emission wavelength at 625 nm. Besides, the probe XT-HZ had excellent water solubility, high selectivity, and good sensitivity for detecting hydrazine. Finally, probe XT-HZ was applied in the imaging of N2H4 in living cells, zebrafish and environmental water samples.
摘要：
肼(N2H4),一种重要的化工原料，改善人们的生活，促进人类进步。肼的使用或泄漏已造成环境污染，影响水，土壤,和生物。肼同时由于其致癌特性而对人类健康存在可能的风险。因此，肼的快速和精确检测在环境研究和生物环境中至关重要。我们制备了一种红色荧光开启探针（XT-HZ）来特异性检测肼。该探针对具有570nm的激发波长和625nm的发射波长的肼(63nM)具有低检测限。此外,探针XT-HZ具有优异的水溶性，高选择性,对肼的检测具有良好的灵敏度。最后,XT-HZ探针用于活细胞中N2H4的成像，斑马鱼和环境水样。
