Fmoc‐Diphenylalanine Self Assembles to a Hydrogel via a Novel Architecture Based on π–π Interlocked β‐Sheets

Abstract

The self assembly of peptide hydrogelators that carry aromatic substituents can be modeled by a novel nanocylindrical architecture. The proposed model suggests that the nanocylinders are formed by anti-parallel β-sheets interlocked by the π-stacking interactions of fluorenyl groups and phenyl rings. This explanation is consistent with the structures observed in TEM and the data obtained by a variety of spectroscopic techniques.
