Bowled over: A family of gem‐difluorinated sumanenes was synthesised, including the highly symmetric hexafluorosumanene (see figure). The favourable columnar structure is maintained upon fluorination. Substitution by electron‐withdrawing substituents increases the bowl depth and results in a large cathodic shift of the reduction potential.
