Columnar assembly formation and metal binding of cyclic tri-beta-peptides having terpyridine ligands.
[reaction: see text] A novel cyclic tri-beta-peptide having terpyridine (tpy) metal ligands was synthesized to investigate its assembly formation and metal complexation. Microscopic observation revealed that this cyclic peptide formed a rod-shaped molecular assembly. The assembly was able to bind Cu(II) because the tpy ligands covered the surface of the crystal, keeping the tpy plane parallel to the ring plane of the cyclic tri-beta-peptide.
