中文摘要：
利用次氯酸根(ClO-)的氧化性质和Cu+与Cu2+不同的配位性质,一种高效的可用于探测ClO-的铜离子化合物CS1被合成出来。通过吸收和发射光谱系统地研究了CS1对ClO-的传感性能。结果表明,在Cu+存在条件下,CS1的光谱强烈受到OCl-影响:最大吸收峰从396 nm红移到545 nm(Δλ=149 nm);520nm处的荧光强度降低近25倍。以Cu+和ClO-为输入信号,以470 nm和396 nm吸收峰比值(A470/A396)为输出信号,构建了一个基于CS1的AND逻辑门,并且可以用乙二胺四乙酸二钠盐(EDTA)对其进行简单重置。
英文摘要：
By utilizing the oxidation property of hypochlorite(ClO-) and different coordinating properties of Cu+ and Cu2 +,a high efficiency ClO-probe compound that based on Cu2 +chemosensor(CS1) was synthesized.The sensing properties of CS1 for ClO-was investigated by UV-Vis and fluorescene spectroscopy.The results showed the spectra of CS1 in the presence of Cu+was highly affected by ClO-:(1) the maximum absorption peak shifted from 396 nm to 545 nm(Δλ = 149 nm);(2) the fluorescence intensity at 520 nm decreased about 25 times.CS1 mimicked an AND logic gate function with Cu+and ClO-as inputs and A 470/ A 396 as output(A = absorbance),and this function could be easily reset by ethylenediaminetetraacetic acid disodium salt(EDTA).
