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。

Colorimetric and fluorimetric chemosensor based on upper rim-functionalized calix[4]arene for selective detection of fluoride ion
A new colorimetric and fluorescent chemosensor for fluoride anion based on calix [4]arene bearing four sulfonamide-fluorenone subunits on the upperrim 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
