RESUMEN
A chiral supramolecular alternate block copolymer has been self-assembled from a ureidopyrimidinone (UPy)-terminated arylamide-based hydrogen bonded foldamer and a structurally flexible pentamer, which is driven by the ion-pair binding of the two arylamide segments toward chiral ammonium and carboxylate guests.

RESUMEN
Inspired by arylamide-based oligomeric foldermers that are stabilized by intramolecular hydrogen bonding, a series of polyamides with intramolecular hydrogen-bonding motifs were synthesized via polycondensation reactions. These polymers can fold into helical conformation different from their linear control. The chirality of helical conformation can further be tuned via acid-base complexation using chiral residues.
