文摘

A novel type of chiral layered supramolecular copolymer with high molecular weight has been assembled from a hydrogen bonded C₆-symmetric zinc porphyrin hexamer and chiral C₃-symmetric pyridine hexadentate linkers driven by multivalent zinc porphyrin鈥損yridine coordination. UV鈥搗is, 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.
