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.
Synthesis and single-molecule studies of a well-defined biomimetic modular multidomain polymer using a peptidomimetic β-sheet module

In the pursuit of advanced biomaterials with combined strength, toughness, and elasticity, a new class of well-defined modular polymers has been synthesized, and their nanomechanical properties have been studied using atomic force microscopy. These polymers are based on a peptidomimetic β-sheet-based double-closed loop (DCL) module, which was designed to overcome the limitation of the modular polymers we reported previously (J. Am. Chem. Soc. 2004, 126, 2059). Single-molecule force-extension experiments revealed the sequential unfolding of these modules as the polymer is stretched, resulting in more regular sawtooth-patterned curves similar to those seen in titin and other biopolymers. The single-molecule data agreed well with computer modeling, which suggested that hydrogen bonding and π-stacking are both involved in the formation of small DCL clusters along the polymer chain.

This paper describes the design, synthesis, and characterization of a hydrogen-bonded molecular duplex (3·4). Two oligoamide molecular strands, 3 and 4, with the complementary hydrogen-bonding sequences ADAADA and DADDAD, respectively, were found to form
