Pillar[5]arene and naphthalimide constructed novel supramolecular sensor for successive detection Fe3+ and F- in water

Abstract

As we all know, due to its high hydration enthalpy, the detection of F- in water is a very difficult task. Herein, we report a novel water soluble self-assembled supramolecualr sensor P5B1 for fluorescent detection Fe3+ and F- in water. The supramolecualr sensor P5B1 was constrcted by the self-assembly of water soluble cationic pillar[5]arene (P5) and novel N-(pyridinium-4-yl)-naphthalimide derivative (B1). The P5B1 could selectively detect Fe3+, more interestingly, by adding Fe3+ into the P5B1, the competitive coordination was introduced into the P5B1 and formed new Fe3+ complexed supramolecular sensor P5B1Fe. The P5B1Fe showed high selectivity and sensitivity for F- in water solution. Moreover, the P5B1-based silica gel plate and test strips for selective detection Fe3+ and F- were prepared, which could not only act as Fe3+ and F- test kits, but also as Fe3+ and F- controlled fluorescent display materials.
