Through‐Space (Cofacial) π‐Delocalization among Multiple Aromatic Centers: Toroidal Conjugation in Hexaphenylbenzene‐like Radical Cations

Pi-Donuts: Eine hoch effektive Konjugation zwischen cofacialen (aromatischen) Redoxzentren durch den Raum liegt in stabilen Hexaanilinylbenzol-Radikalkationen vor (1.+; die π-Konjugation ist durch das Toroid angedeutet). Die Radikalkationen liefern ungewöhnliche Intervalenz-Absorptionsbanden und wurden mit einer Mulliken-Hush-Formulierung quantitativ analysiert.
