Quantifying chloride binding and salt extraction with poly(methyl methacrylate) copolymers bearing aryl-triazoles as anion receptor side chains

摘要

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.
