Abstract
A novel approach for the detection and separation of toxic ions was successfully developed via the introduction of competitive reactions into a long-alkyl-chained acylhydrazone-based coumarin supramolecular polymer, chemosensor OGC (3%, n-BuOH/H<sub>2</sub>O), which showed sequential detection and separation of CN<sup>-</sup>, Fe<sup>3+</sup> and S<sup>2-</sup>, Ag<sup>+</sup> in the gel state with high selectivity and sensitivity. Moreover, the ion-responsive films were prepared for the convenient and continuous detection of CN<sup>-</sup>, Fe<sup>3+</sup> and S<sup>2-</sup>, Ag<sup>+</sup> in water solution.
