Hydrazine is a highly reactive inorganic compound that is commonly used as a thruster propellant in rocket fuels. In this report, the synthesis of a naphthofluorescein-based simple, sensitive, and selective colorimetric and fluorescent probe for the qualitative and quantitative determination of hydrazine is described. An ultrasensitive NIR probe is employed for the nanomolar detection of hydrazine with real-time applicability. The probe is capable of detecting hydrazine in a completely aqueous medium without the interference of other analytes. The probe reacts selectively with hydrazine and exhibits turn-on NIR emission with quantum yields ranging from Φ = 0.0011 to Φ = 0.5338. This enables the probe to selectively detect extremely low concentrations of hydrazine (∼47 nM). As a consequence, practical utility of the probe is greatly augmented. Eco-friendly test strips were prepared to monitor the hydrazine under aqueous and vapor phases. The potential of the probe was verified by monitoring the presence of hydrazine in a living system by fluorescence bioimaging studies of living cells.

近红外发射探针在生物成像和气相肼的实时检测中在完全水性介质中检测纳摩尔肼
肼是一种高反应性的无机化合物，通常用作火箭燃料中的推进器推进剂。在本报告中，描述了基于萘荧光素的简单，灵敏和选择性比色和荧光探针的合成，用于定性和定量测定肼。超灵敏的NIR探针可实时检测肼的纳摩尔浓度。该探针能够在完全水性的介质中检测肼，而不会受到其他分析物的干扰。探针与肼选择性反应，并显示开通的NIR发射，量子产率范围为Φ= 0.0011至Φ= 0.5338。这使探针能够选择性地检测极低浓度的肼（〜47 nM）。结果，大大提高了探针的实用性。制备了环保试纸以监测水相和气相中的肼。通过对活细胞进行荧光生物成像研究，通过监测活体系统中肼的存在来验证探针的潜力。
