| Popis: | To explore whether chalcogen bonding was able to drive the formation of supramolecular helices, alanine-based azapeptides containing a β-turn structure, with a thiophene group, respectively, incorporated in the N- or C-terminus, were employed as helical building blocks. While the former derivative formed a supramolecular M-helix via intermolecular S⋯S chalcogen bonding in crystals, the latter formed P-helix via intermolecular S⋯O chalcogen bonding. |
