Abstract

Small aromatic dipeptides can self-assemble into supramolecular bioinspired peptide nanotubes. Nanoscale dimensions of their nanocrystalline building blocks and their space symmetry is the origin for exceptional physical properties of these nanotubular structures, such as quantum confinement and ferroelectric-related phenomena (piezoelectricity, second harmonic generation and spontaneous polarization). In this work we study basic intrinsic physical properties in diphenylalanine-based peptide nanostructures, and follow their variation during the phase transition process.
