摘要

利用次氯酸根(ClO

)的氧化性质和Cu

与Cu

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 (

=149 nm); 520 nm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(

470

396

)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。

Abstract

By utilizing the oxidation property of hypochlorite (ClO

) and different coordinating properties of Cu

and Cu

a high efficiency ClO

probe compound that based on Cu

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 (

=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

470

396

as output (

=absorbance)

and this function could be easily reset by ethylenediaminetetraacetic acid disodium salt (EDTA).
