AB A route to generate cyclacenes by on-surfacesynthesis is explored. We started by synthesizing two tetraepoxycyclacenesby sequences of Diels–Alder cycloadditions.Subsequently, these molecules were deposited onto Cu(111)and scanning-tunneling-microscopy(STM)-based atommanipulation was employed to dissociate the oxygen atoms.Atomic force microscopy (AFM) with CO-functionalized tipsenabled the detailed characterization of the reaction productsand revealed that, at most, two oxygens per molecule could beremoved. Importantly, our experimental results suggest that thegeneration of cyclacenes by the described route might bepossible for larger epoxycyclacenes
