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.
