TL;DR: The recent advances in supramolecular helical assemblies formed from chiral and achiral small molecules, oligomers (foldamers), and helical and nonhelical polymers from the viewpoints of their formations with unique chiral phenomena, such as amplification of chirality during the dynamic helically assembled processes, properties, and specific functionalities.

TL;DR: The remote control of the dynamic chirality of metal centres, coordinated by 2,2'-bipyridine ligands bearing dynamic helical oligopeptides, is reported, and it is shown that when a mixture of chiral and achiral peptide ligands is used, both the chiralities of the metal centre and that of the a chiral oligopePTide helices are significantly amplified.

TL;DR: Mechanistic studies indicate the memory displayed by this capsule to be the result of effective stereochemical communication between the metal centers mediated by the rigid 3-fold-symmetric faces, in combination with a stepwise substitution mechanism.

TL;DR: One for all, all for one: A self-assembled M 4L 6 cage, incorporating small amounts of enantiopure subcomponents at the peripheries, forms predominantly with a one-handed twist at all metal centers as mentioned in this paper.

TL;DR: A series of large, optically active Fe(4)L(6) cages was prepared from linear 5,5'-bis(2-formylpyridines) incorporating varying numbers of oligo-p-xylene spacers, chiral amines, and Fe(II), and metal-centered stereochemistry was not observed to affect the axial stereochemistry of the ligands.
