基于罗丹明衍生物的Cu~(2+)荧光/比色传感器
|
摘要
以苯胺、罗丹明为原料,合成出可以通过紫外吸收光谱和荧光光谱双重变化用来识别铜离子的探针,加入铜离子后,溶液的颜色由浅黄色变为红色,荧光由无色变为橙黄色.通过荧光、紫外等表征表明了该探针对铜离子显现出高的灵敏度和选择性.
In this paper,aniline and rhodamine are used as materials synthesis probe that can be used to identify copper ions by double changes in absorption and fluorescence spectra.After adding copper ions,the color of the solution can be visually observed to changes from light yellow to red,fluorescence changes from colorless to orange.The fluorescence and UV spectra indicate that the probe exhibits high selectivity and sensitivity to copper ions.
