Highly Stable Chiral (A)6-B Supramolecular Copolymers: A Multivalency-Based Self-Assembly Process

A novel type of chiral layered supramolecular copolymer with high molecular weight has been assembled from a hydrogen bonded C-6-symmetric zinc porphyrin hexamer and chiral C-3-symmetric pyridine hexadentate linkers driven by multivalent zinc porphyrin-pyridine coordination. UV-vis, circular dichroism, and static light scattering experiments revealed that the formation of the layered supramolecular copolymers is at first dynamically controlled and then becomes thermodynamically controlled.
