One-way atropisomerism: ineso-(4-Butoxypyrid-3-yl)-substituted Zn II porphyrins self-assemble to form zigzagshaped cyclic hexamers, whereas the meso-meso-linked ZnII diporphyrins 1 undergo self-sorting self-assembly to form different assemblies. Upon heating, entropically driven one-way atropisomerism to 1in-in has been achieved through fragmentary reconstitution of supramolecular aggregates.
