合成了一种新型的萘酰亚胺杯[4]芳烃荧光化学传感器，该传感器具有高选择性的Cu ~（2+）和F ~-的双面荧光化学传感器。该化学传感器显示出选择性的荧光猝灭效应，只有铜2+中的各种金属离子。另一方面，在各种阴离子中，标题化学传感器仅对F-表现出选择性荧光猝灭效应。利用荧光变化和H-1 NMR实验进一步研究了与F-的结合模式。(C)2007爱思唯尔有限公司版权所有。
A new naphthalimide-calix[4]arene was synthesized as a two-faced and highly selective fluorescent chemosensor for Cu2+ or F-. This chemosensor displayed a selective fluorescence quenching effect only with Cu2+ among the various metal ions. On the other hand, among the various anions, the title chemosensor displayed a selective fluorescence quenching effect only with F-. The binding mode with F- was further investigated using fluorescence changes and H-1 NMR experiments. (C) 2007 Elsevier Ltd. All rights reserved.
