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.

摘要

带有多个烷基侧链的寡酰胺双螺旋被发现可作为芳族溶剂的凝胶剂。双链骨架对于分子双螺旋的分级自组装成高纵横比纤维是必不可少的。所展示的凝胶能力可以扩展到具有不同氢键序列的类似氢键双螺旋的大家族，从而为基于超分子和/或动态共价方法开发各种潜在的凝胶剂提供了独特的平台。
