A coiled structure of meso ‐pentafluorophenyl‐substituted [62]tetradecaphyrin 1 was revealed by X‐ray structural analysis. Synthetic protocols were devised to form mono‐ and bis‐Zn II complexes, 1 Zn and 1 Zn 2 , selectively. The former displayed a trigonal‐bipyramidal pentacoordinated Zn II ion as a rare case and a cyclic voltammogram exhibiting eleven reversible redox waves. The latter showed a Ci ‐symmetric structure with modest Hückel aromaticity owing to a 62 π‐electronic circuit as the largest aromatic molecule to date.
