A new fluorescent (TMCD) probe has been developed for the detection of hypochlorous acid (HClO) with sensitive response toward HClO. The probe color changes from green to yellow during the addition of HClO following PET OFF mechanism. The chemodosimeter promoted a selective response to hypochlorous acid compared to other ROS and RNS with a detection limit at 89 nM. The binding mechanism of probe with guest molecules has been confirmed by NMR spectroscopy, Mass spectroscopy and DFT calculations.
新开发的荧光(TMCD)探针可用于检测次氯酸(HClO),对 HClO 反应灵敏。在加入 HClO 的过程中,探针的颜色会根据 PET OFF 机制从绿色变为黄色。与其他 ROS 和 RNS 相比,该化学计量器对次氯酸具有选择性响应,检测限为 89 nM。核磁共振光谱、质谱和 DFT 计算证实了探针与客体分子的结合机制。
