Abstract

Here we report on using small unnatural helical beta peptides to form higher order geometries. These peptides are known to self-assemble by supramolecular recognition, via a unique 3-point H-bonding motif. This self-assembly pattern leads to unprecedented head-to-tail self-assembly, thus continuing the intramolecular helix into a fibrous superstructure. The smallest peptide still capable of self-assembly had a sequence of only three beta amino acids. We demonstrated a hierarchical self-assembly process, which can be designed to form macroscopic silk-like threads as well as complex nanometer scale surface structures. We have achieved radial as well as parallel geometries. Both the synthesis and the derivatization of the fibres is relatively straigthforward, making this platform technology ideally suited for the highly exacting requirements of materials science.
