Extremely nonplanar permethoxylated hexa‐ peri ‐hexabenzocoronene can be prepared by using a facile ferric chloride cyclodehydrogenation procedure. The combination of a rigid “double‐concave” aromatic core with 18 flexible methoxy groups at the periphery makes it a remarkable host molecule, as revealed by single‐crystal analysis of its crystalline inclusion complexes with hexafluorobenzene and fullerene guest molecules (see crystal structure).
