Abstract

original image

π Stacking between the β sheets: A newly designed π-conjugated peptide can be assembled into a one-dimensional nanostructure with strong π–π intermolecular electronic communication. A nanoelectronic device based on the achieved individual nanostructure was used to measure conductivity (see graphic).
