Abstract: The present invention discloses a family of cyclic peptide monomers and supramolecular cyclic peptide structures comprising chromophore residues which possess electronic and electro-optic properties for producing molecular scale electronic and photonic devices made from such materials. More particularly, this invention provides for cyclic peptide nanotube structures formed from a plurality of stacked cyclic peptides comprising chromophore residues that provide molecular scale electronic conductivity and non linear optical behavior.
