Herein, we presented two novel turn-on colorimetric and fluorescent probes based on a F− triggered SiO bond cleavage reaction, which displayed several desired properties for the quantitative detection for F−, such as high specificity, rapid response time (within 3 min) and naked-eye visualization. The fluorescence intensity at 574 nm (absorbance at 544 nm) of the solution was found to increase linearly
在此,我们提出了一种基于A F两种新颖的导通比色和荧光探针-触发的Si O键裂解反应,其显示若干所需性质的定量检测与F -在3分钟内,如高特异性,快速响应时间( )和肉眼可视化。在溶液的574纳米(吸光度544 nm)的荧光强度被发现与F的浓度线性增加-与所述检测限(0.00-30.0μM)估计为0.47μM/ 0.48μM。基于这些优异的光学性能,所述探针用于监测˚F -实际水样和茶样中令人满意。此外,它已成功地用于F的荧光成像-在活裸鼠,这表明它可以作为一个功能强大的工具来预测和探索F的生物学功能-在生理和病理过程。
