摘要/Abstract

以4-羟基氟硼二吡咯为荧光团, 叔丁基二苯基硅基(TBDPS)作活泼羟基的保护基, 设计合成了一种新颖的基于氟离子切断硅氧键, 引发释放的氟硼二吡咯类氟离子荧光探针R. 光谱实验研究表明, 该荧光探针和氟离子作用后, 紫外吸收光谱在605 nm处出现新的吸收峰, 含R的溶液由橙黄色变成蓝色; 荧光发射光谱中在514 nm处最大发射峰出现下降, 荧光颜色由绿色变成荧光淬灭. 此外, 将荧光探针R应用于试纸条件下也能实现对氟离子的裸眼检测.

4-Hydroxy-fluoroborodipyrrole is used as fluorophore, and tert-butyldiphenylsilyl (TBDPS) is used as protective group for active hydroxyl groups. A novel fluoroborodipyrrole type of fluoride ion fluorescent probeR based on fluorine ion causing cleavage of Si—O bond to trigger cascade releasing was designed and synthesized. Spectral experimental studies showed that after the interaction of the fluorescent probe and fluoride ion, a new absorption peak appeared at 605 nm in the ultraviolet absorption spectrum. The solution includingR changed from orange to blue, the maximum emission peak at 514 nm in the fluorescence emission spectrum decreased, and the fluorescence color changed from green to fluorescence quenching. In addition, the use of fluorescent probeR under the test paper conditions also enables the naked eye detection of fluoride ions.
Key words: fluoroborodipyrrole, fluorescent probe, fluoride ion, detection
