This work facilitates detection of bivalent copper ion by a simple Schiff base probe QNH based on a quinoxaline-naphthaldehyde framework. The detailed study in absorption spectroscopy and theoretical aspects and crystal study of the probe and probe-copper complex has been discussed. The detection limit of the probe in the presence of Cu is 0.45 µM in HEPES-buffer/acetonitrile (3/7, /) medium for absorption study. The reversibility of the probe-copper complex has been investigated by EDTA. The selective visual detection of copper has been established also in gel form.
这项工作通过基于喹喔啉-萘醛骨架的简单希夫碱探针 QNH 促进了二价铜离子的检测。已经讨论了探针和探针-铜配合物在吸收光谱和理论方面以及晶体研究方面的详细研究。在存在 Cu 的情况下，探针在 HEPES-缓冲液/乙腈（3/7，/）介质中的吸收研究中的检测限为 0.45µM。通过 EDTA 研究了探针-铜配合物的可逆性。还在凝胶形式中建立了铜的选择性可视化检测。
