A new colorimetric and fluorescent chemosensor for fluoride anion based on calix [4]arene bearing four sulfonamide-fluorenone subunits on the upper rim was conveniently synthesized. It showed a remarkable color change as well as the fluorescence quenching upon addition of F⁻ even in the presence of a wide range of anions in DMSO. The binding property of L with F⁻ was studied by a combination of various spectroscopic techniques, such as absorption and emission titration, Job's plot and ¹H NMR titration. It is anticipated that this design with functional group attached to upper rim of calix[4]arene platform can provide a new approach for the development of F⁻ chemosensor.

方便地合成了一种基于杯[4]芳烃的氟阴离子比色荧光化学传感器，该杯[4]芳烃在上缘带有四个磺酰胺-芴酮亚基。即使在 DMSO 中存在多种阴离子的情况下，它也显示出显着的颜色变化以及在添加 F ^-后荧光猝灭。L与 F ^-的结合特性通过各种光谱技术的组合进行研究，例如吸收和发射滴定、Job's 图和¹ H NMR 滴定。预计这种将官能团连接到杯[4]芳烃平台上缘的设计可以为F ^-化学传感器的开发提供新的途径。
