A novel near-infrared fluorescent probe CyOE based on hemicyanine dye containing acetyl as a recognition site is reported. The probe CyOE shows high selectivity and sensitivity (LOD = 82 nM, 2.58 ppb), as well as good water solubility and quantitative detectability of hydrazine in the concentration range of 0–75 μM (R² = 0.993). Moreover, CyOE has a significant increase in fluorescence at 735 nm with the addition of N₂H₄, which provides a rapid, colorimetric and gas-phase detection method for N₂H₄ in both aqueous solution and real water samples. In addition, CyOE is successfully utilized to visualize hydrazine in cells with low cytotoxicity and high cell permeability.

报道了一种以乙酰基为识别位​​点的基于半花青染料的新型近红外荧光探针CyOE。CyOE 探针具有高选择性和灵敏度（LOD = 82 nM，2.58 ppb），在 0-75 μM 浓度范围内（R ²  = 0.993）具有良好的水溶性和肼定量检测能力。_{此外，添加 N 2} H ₄后，CyOE 在 735 nm 处的荧光显着增加，这为水溶液和真实水样中的 N ₂ H ₄提供了一种快速、比色和气相检测方法。此外，CyOE 还成功地用于观察细胞中的肼，具有低细胞毒性和高细胞通透性。
