在改进的 Rothemund-Lindsey 条件下，由 3, 4-二氟吡咯和五氟苯甲醛合成的全氟内消旋芳基取代的扩展卟啉发现了扭曲的 8 字形结构。 [26]六菲林的晶体结构（见图）由两个几乎平面的三吡咯亚基组成，它们倾斜约60°，其中π电子系统的键长明显变化。
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.
