Twisted figure‐of‐eight structures are found for the perfluorinated meso ‐aryl‐substituted expanded porphyrins synthesized from 3,4‐difluoropyrrole and pentafluorobenzaldehyde under modified Rothemund–Lindsey conditions. The crystal structure of the [26]hexaphyrin (see picture) consists of two almost planar tripyrrolic subunits which are tilted by approximately 60° in which a distinct alternation in the bond lengths of the π‐electronic system is evident.
