Exploration of Structured Symmetric Cyclic Peptides as Ligands for Metal-Organic Frameworks.

ABSTRACT: Despite remarkable advances in the assembly of highly structured coordination polymers and metal-organic frameworks, the rational design of such materials using more conformationally flexible organic ligands such as peptides remains challenging. In an effort to make the design of such materials fully programmable, we first developed a computational design method for generating metal-mediated 3D frameworks using rigid and symmetric peptide macrocycles with metal-coordinating sidechains. We solved the structures of six crystalline networks involving conformationally constrained 6 to 12 residue cyclic peptides with C2, C3, and S2 internal symmetry and three different types of metals (Zn²⁺, Co²⁺, or Cu²⁺) by single-crystal X-ray diffraction, which reveals how t
