Abstract

Copolymers of methyl methacrylate and aryl-triazole based anion receptors were quantitatively analyzed. Transfer of structural features (1 : 1 and 2 : 1 complexes) and Cl(-) affinities from the parent receptors was demonstrated. Cl(-)-induced cross-linking changed the polymer's hydrodynamic radius. Extraction of tetrapropylammonium Cl(-) from water to dichloromethane was enhanced over PMMA.
