is a lack of AIE probes for hypochlorite detection. In this study, two AIE probes based on benzothiazole derivatives (BTD-1 and BTD-2) were designed and synthesized. Both probes exhibited good AIE charac-teristics and allowed different visual detection for hypochlorite. Additionally, the two probes could be used to detect endogenous hypochlorite in mitochondria and were successfully applied for in vivo
次氯酸盐是在生物体内形成的重要活性氧,快速,高灵敏度地检测痕量次氯酸盐对于早期了解由次氯酸盐浓度异常引起的疾病机理具有重要意义。尽管聚集诱导发射(AIE)探针对于检测生物体中的分析物非常重要,但仍缺乏用于次氯酸盐检测的AIE探针。在这项研究中,设计并合成了两种基于苯并噻唑衍生物的AIE探针(BTD-1和BTD-2)。两种探针均显示出良好的AIE特性,并允许对次氯酸盐进行不同的目测检测。此外,这两种探针可用于检测线粒体内的内源性次氯酸盐,并已成功应用于体内 斑马鱼的次氯酸盐成像。
