设计合成了一种可逆的Cu~(2+)比色探针3,5-二氯水杨醛缩罗丹明B酰腙(L),采用IR、~1H NMR、~(13)C NMR、元素分析和X射线单晶衍射对其结构进行了表征。利用紫外-可见吸收光谱考察了探针对金属离子的识别性能,实验结果表明,探针L在乙腈/乌洛托品(pH 5.6)缓冲体系中,当加入Cu~(2+)后,溶液从无色变为玫瑰红色,而加入其它金属离子,溶液颜色几乎无变化,可实现3,5-二氯水杨醛缩罗丹明B酰腙探针对Cu~(2+)高灵敏、专一显色响应,最低检测限达到了9.30×10~(-8) mol?L~(-1)。

A novel colorimetric probe, 3,5-dichlorosalicylaldehyde-omicron-rhodamine B hydrazone (L), for Cu2+ was designed, synthesized. Its structure was characterized with IR, H-1 NMR, C-13 NMR, elemental analysis and X-ray crystal diffraction. The binding property of the probe with Cu2+ was examined by UV-Vis spectroscopy. The result showed in acetonitrile/methenamine (pH 5.6) buffer system, when Cu2+ was added to the solution of 3,5-dichlorosalicylaldehyde-omicron-rhodamine B hydrazone, a dramatic color change from colorless to rose red was observed, while the other metal ions did not cause noticeab...
