Oligoamide Duplexes as Organogelators

Abstract

Oligoamide duplexes carrying multiple alkyl side chains were found to serve as gelators for aromatic solvents. The double-stranded backbone was essential for the hierarchical self-assembly of the molecular duplex into fibers of high aspect ratios. The demonstrated gelating abilities may be extended to a large family of analogous H-bonded duplexes having different H-bonding sequences, leading to a unique platform for developing a diverse variety of potential gelators based on a supramolecular and/or a dynamic covalent approach.
