| Abstract: | 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‐ZnII complexes, 1 Zn and 1 Zn2 , selectively. The former displayed a trigonal‐bipyramidal pentacoordinated ZnII 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. |
