β-四苯基meso-六（五氟苯基）取代的[26]六卟啉3在矩形和8字形形状之间具有构象柔性，并且其双电子还原的[28]六卟啉4具有8字形构象，其在质子化后改变为具有明显的Mobius芳香性的扭曲构象。
beta-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 Mobius aromaticity.
