It stacks up nicely : Exposure of dihydrogen sulfate salts of appropriately substituted cyclo[8]pyrroles to electron‐deficient acceptor molecules gives discotic liquid crystals. The columnar mesophase structures are stabilized by electron‐donor/electron‐acceptor interactions (see picture; red: trinitrobenzene, green: cyclo[8]pyrrole cores, yellow: sulfate ions, gray: volume occupied by the substituents).
