Selective Formation of a Single Atropisomer of <i>meso</i>–<i>meso</i>‐Linked Zn^II Diporphyrin through Supramolecular Self‐Assembly

Abstract

One-way atropisomerism: meso-(4-Butoxypyrid-3-yl)-substituted ZnII porphyrins self-assemble to form zigzag-shaped 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.
