Switching Aromaticity : Conformations of [32]heptaphyrins(1.1.1.1.1.1.1) are dependent upon meso‐aryl substituents, solvents, temperature, and protonation. Particularly, protonation of meso‐pentafluorophenyl‐substituted [32]heptaphyrin triggers conformational changes to form twisted aromatic Möbius structures (see picture), even at room temperature.
