β-Tetraphenyl meso-hexakis(pentafluorophenyl) substituted [26]hexaphyrin 3 is conformationally flexible between rectangular and figure-of-eight shapes and its two-electron reduced [28]hexaphyrin 4 takes figure-of-eight conformations, which are changed, upon protonation, to twisted conformations with distinct Möbius aromaticity.
