The synthesis of molecular propellers featuring low‐energy activation barriers of the racemization reaction remains elusive. The trimerization reaction of enantiomerically‐pure binaphthols with hexakis(bromomethyl)benzene enabled the one‐step preparation of enantiomerically‐pure molecular propellers, in which three binaphthyl rings are held together through dioxecine rings. X‐ray diffraction analysis revealed that the six naphthyl moieties adopt a folded conformation, which shows a striking similarity to the mythological Sicilian symbol of Trinacria.
