A new folder: The electropositive CH groups of diaryl triazoles interact favourably with chloride, leading to anion-induced helical folding in aryl triazole oligomers. Triazoles thus provide an alternative to conventional protic hydrogen bonds and coordination complexes as functional components in anion receptors.
