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.
The stackable cyclic peptide is represented by the general formula of m repeating amino acid residue pairs where n equals 1 or 2, m equals 4 or 6, R
A
and R
D
are either H, CH
3
or an alkyl, where at least one R
B
or R
E
in at least one repeating residue pair is a chromophore, where R
C
and R
F
are either H, CH
3
or a polar or non-polar organic functional group used for controlling peptide stacking, nanotube formation and solubility, and where a first adjacent amino acid residue has an α-carbon chirality of L and a second adjacent amino acid residue has an α-carbon chirality of D.
