of 1 with .OH leads to a larger π‐conjugation formation and near‐infrared fluorescence off–on response. The capability of probe 1 has been demonstrated by imaging .OH generated in living cells under iron autoxidation as well as various stimuli, which reveals that the basal level of .OH in RAW 264.7 cells is lower than that in HeLa cells. The superior analytical performance of probe 1 makes it useful
第一个敏感的荧光。OH探针(1),能够监测痕量的产生。介绍了铁自氧化过程中的OH。探针1是通过利用独特的芳香羟基化和亲电性设计的。OH,并通过在花菁荧光染料中引入强供电子甲氧基来增强对的捕集能力。哦。1与的反应。OH导致更大的π共轭形成和近红外荧光关闭响应。探头1的功能已通过成像证明。在铁自氧化以及各种刺激下在活细胞中产生的OH,这表明OH的基础水平。RAW 264.7细胞中的OH低于HeLa细胞中的OH。探针1的出色分析性能使其可用于检测痕量。OH在某些与铁自氧化有关的重要生理和病理过程中。
