A novel supramolecular polymer gel-based long-alkyl-chain-functionalized coumarin acylhydrazone for the sequential detection and separation of toxic ions

Abstract

A novel long-alkyl-chains functionalized supramolecular polymer gel <bold>OGC</bold> was constructed, which shows successive recognition of CN⁻ and S²⁻ to Fe³⁺ and Ag⁺. So, our study provided a new methods to detect deferent toxic ions <italic>via</italic> single chemosensor.
