Exploiting the CH-π interactions in supramolecular hydrogels of aromatic carbohydrate amphiphiles [PDF]

, 2011
A novel class of supramolecular hydrogels derived from amino sugars is reported, where the self-assembly of aromatic carbohydrate amphiphiles is driven by CH-π interactions, rather than π–π stacking and H-bonding associated with gelators based on ...

Self-assembly of minimal peptoid sequences [PDF]

, 2020
Peptoids are biofunctional N-substituted glycine peptidomimics. Their self-assembly is of fundamental interest because they demonstrate alternatives to conventional peptide structures based on backbone chirality and beta-sheet hydrogen bonding.
