Hypochlorous acid (HOCl) and peroxynitrite (ONOO-) are two of the most important reactive species and associated with various diseases in various physiological and pathological processes. Nonetheless, many of their roles are still vague due to the shortage of methods for simultaneously detecting HOCl and ONOO-. Herein, three simple yet useful fluorogenic probes, LG-1, LG-2 and LG-3, have been fabricated with facile synthesis route and used to monitor the coexistence of HOCl and ONOO- as AND-based logic gate fluorescent probe firstly. LG-1 and LG-2, which consists of 1,3-oxathiolane group and boronate group respectively, were designed to verify the capacity of monitoring HOCl and ONOO- without interference from each other. The result showed that these two groups are perfect reaction sites of detecting HOCl and ONOO- respectively via specific analyte-induced reactions. Hence, LG-3, which is attached by these two groups to suppress the fluorophore core, can response to HOCl and ONOO- simultaneously without mutual interference and generate the significant time-dependent fluorescence enhancement. By investigating the absorption and fluorescence properties of LG-3 towards HOCl and ONOO- individually and collectively, the result confirmed clearly that LG-3 has the capacity of monitoring the coexistence of HOCl and ONOO-, which could act as a two-input AND-based logic gate fluorescent probe.

基于AND逻辑门的荧光探针可同时检测过氧亚硝酸盐和次氯酸。

次氯酸(HOCl)和过氧亚硝酸盐(ONOO-)是最重要的两个反应物种,在各种生理和病理过程中与多种疾病有关。但是,由于缺乏同时检测HOCl和ONOO-的方法,它们的许多作用仍然不清楚。在此,以简便的合成路线制备了三种简单而有用的荧光探针LG-1,LG-2和LG-3,它们首先作为基于AND的逻辑门荧光探针用于监测HOC1和ONOO-的共存。LG-1和LG-2分别由1,3-氧杂硫杂环戊烷基团和硼酸酯基团组成,旨在验证在不互相干扰的情况下监控HOCl和ONOO-的能力。结果表明,这两组分别是通过特异性分析物诱导的反应检测HOCl和ONOO-的理想反应位点。因此,被这两个基团连接以抑制荧光团核心的LG-3可以同时响应HOCl和ONOO-,而不会相互干扰,并产生显着的时间依赖性荧光增强。通过分别和共同研究LG-3对HOCl和ONOO-的吸收和荧光性质,结果明确证实LG-3具有监测HOCl和ONOO-并存的能力,可以作为两个输入的AND基于逻辑门的荧光探针。可以同时响应HOCl和ONOO-,而不会相互干扰,并产生显着的时间依赖性荧光增强。通过分别和共同研究LG-3对HOCl和ONOO-的吸收和荧光性质,结果明确证实LG-3具有监测HOCl和ONOO-并存的能力,可以作为两个输入的AND基于逻辑门的荧光探针。可以同时响应HOCl和ONOO-,而不会相互干扰,并产生显着的时间依赖性荧光增强。通过分别和共同研究LG-3对HOCl和ONOO-的吸收和荧光性质,结果明确证实LG-3具有监测HOCl和ONOO-并存的能力,可以作为两个输入的AND基于逻辑门的荧光探针。
