Abstract
In the present work, we have synthesized a new water soluble colorless chemical compound 7-O-tert-butyldiphenylsilyl-4-methylcoumarin (TBDPSC) that releases fluorescent molecules imparting blue fluorescence to the solution, upon interaction with fluoride ions in water. The blue fluorescence can be visualized using simple hand held ultraviolet (UV) lamps. TBDPSC has excellent sensitivity and selectivity towards fluoride and our results indicate that fluoride concentrations as low as 0.2 mg/L can be accurately detected within a few seconds. Fluoride testing with TBDPSC is simple and rapid compared to the conventional methodologies without the requirement of trained personnel. Hence, the present fluoride detection method can be easily field deployable and particularly useful for monitoring water quality in limited resource communities.
在本工作中，我们合成了一种新的水溶性无色化合物7- o -叔丁基二苯基硅基-4-甲基香豆素(TBDPSC)，该化合物与水中的氟离子相互作用，释放荧光分子，向溶液中注入蓝色荧光。蓝色荧光可以用简单的手持紫外线灯观察。TBDPSC对氟化物具有良好的灵敏度和选择性，实验结果表明，低至0.2 mg/L的氟化物浓度可以在几秒内准确检测到。与传统方法相比，TBDPSC检测氟化物简单快速，不需要训练有素的人员。因此，目前的氟化物检测方法可以很容易地在实地部署，对监测资源有限社区的水质特别有用。
