Pi and doughnuts: Highly effective through-space conjugation among cofacial (aromatic) redox centers is established in stable hexaanilinylbenzene radical cations (1.+; π conjugation shown by toroid). The radical cations show unusual intervalence absorption bands and are quantitatively analyzed by Mulliken–Hush formulation.
