title: Aryl-triazole foldamers incorporating a pyridinium motif for halide anion binding in aqueous media.
abstract: Aryl-triazole oligomers incorporating a pyridinium motif have been synthesized from their pyridine precursors. Anion binding studies show that methylation of the pyridine units can significantly enhance the halide anion affinities of the folded oligomers so that the foldamers are capable of binding halide anions in aqueous solutions.
