Abstract

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