次氯酸是活细胞中的活性氧之一，在免疫系统中发挥着关键作用。在本文中，我们提出了一种利用发光肟（1，“开”）与其相应的不发光醛（2，“关”）的氧化脱肟反应，以高选择性和灵敏度检测次氯酸盐（OCl-）的简单方法。所得结果表明，在某些分析物存在的情况下，利用与发光团相连的受体的吸电子能力的可控调节，伴随着荧光信号从“开”到“关”的变化，可能是开发许多具有良好性能的新型化学传感器的好方法。 (C) 2009 Elsevier B.V. 保留所有权利。
Hypochlorous acid is one of the reactive oxygen species in living cells, and plays critical roles in the immune system. In this paper, we present a simple method to detect hypochlorite (OCl-) with high selectivity and sensitivity, by utilizing the oxidative deoximation reaction of luminescent oxim (1, "on") to its corresponding nonluminescent aldehyde (2, "off"). The obtained results demonstrated that the utilization of the controllable adjustment of the electron-withdrawing ability of the acceptors linked to a luminophore in the presence of some analytes, accompanying with the changed fluorescent signal from "on" to "off", might be a good approach to develop many new chemosensors with good performance.
