Electronically active biomaterials via directed peptide self-assembly: Redox-promoted self-assembly of an eight-residue cyclic D,L-α-peptide bearing four 1,4,5,8-naphthalenetetracarboxylic diimide (NDI) side chains results in the formation of electronically delocalized peptide nanotubes hundreds of nanometers in length (see Figure). This supramolecular approach provides a rational basis for the design and fabrication of one-dimensional materials with potential utility in optical and electronic devices.
