Highly Stable Chiral (A)_6-B Supramolecular Copolymers:A Multivalency-Based Self-Assembly Process

摘要

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.
