The design, synthesis, and structural analysis of two macrocyclic D,L-alternating hexapyrrolinones have been achieved. These cyclic peptide mimics adopt a flat, hexagonal conformation, stabilized by intramolecular hydrogen bonding between adjacent pyrrolinone rings. Extensive NMR studies and X-ray analysis reveal, respectively, that the macrocyclic hexapyrrolinones aggregate in solution and in the solid state form staggered stacked nanotube-like assemblies.
