Design of self-assembling peptide nanotubes with delocalized electronic states Academic Article uri icon


  • A central consideration in bottom-up approaches aimed at the design and fabrication of nanoscale functional materials is the ability to predictably associate the properties of building blocks at the molecular level to the materials largescale order and function. In this regard, the principles of supramolecular chemistry have become increasingly useful in materials design, including the fabrication of electronic systems.[1, 2] Here we describe an eight-residue cyclic d, l-αpeptide bearing four cationic 1, 4, 5, 8-naphthalenetetracarboxylic diimide (NDI) side chains that undergoes redoxtriggered self-assembly in aqueous solution into peptide nanotubes,[3] possessing highly delocalized electronic states. Using this approach, isolated peptide nanotubes hundreds of nanometers in length can be obtained and adsorbed onto solid surfaces. The studies described here provide a rational …
