A thin-layered chromatography plate prepared from naphthalimide-based receptor immobilized SiO2 nanoparticles as a portable chemosensor and adsorbent for Pb2+

초록

Fluorogenic naphthalimide-functionalized SiO2 nanoparticles have been easily prepared by intermolecular hydrogen-bonding interactions. Their ability to detect and remove metal ions was evaluated by fluorophotometry. The nanoparticles exhibited high affinity and selectivity for Pb2+ over other competing metal ions. Furthermore, a thin-layered chromatography (TLC) plate modified with immobilized 1 detected Pb2+ in aqueous solution.
