Formation of two types of [4]12-catenane. a Schematic representation of the formation of [4]12-catenane 2 by Ag(I) ion-mediated folding and assembly of tripeptide ligand 1, which was previously reported by our group16. b New [4]12-catenane topology 4, obtained through the same folding-and-assembly strategy but using tripeptide ligand 3. c Four Ag3(3)3 macrocyclic components based on the PII-helix conformation extracted from the structure of 4
