physiological processes. It is significant to detect HClO in mitochondria for getting meaningful physiological and pathological information. However, adequate tools to detect HClO with emissions in two channels are rarely reported. To achieve this target, in this work, a “turn-off” visual and near infrared (NIR) fluorescent dual emission probe D6 based on polyhedral oligomeric silsesquioxanes (POSS) was successfully
次氯酸(HClO)与许多疾病密切相关,是生理过程中不可避免的一部分。检测线粒体中的HClO对于获取有意义的生理和病理信息具有重要意义。然而,很少有足够的工具来检测在两个通道中排放的 HClO。为了实现这一目标,在这项工作中,成功设计并合成了一种基于多面体低聚倍半
硅氧烷(POSS)的“关闭”可见光和近红外(NIR)荧光双发射探针D6 。D6对 HClO 显示出高选择性和灵敏度。值得注意的是,由于 POSS 笼的帮助,D6的发射波长达到了 820 nm。此外,
生物成像实验清楚地表明探针D6 促进了活HepG2细胞和斑马鱼模型中外源性和内源性HClO的可视化。
