Toroidal hopping of a single hole through the circularly-arrayed naphthyl groups in hexanaphthylbenzene cation radical.
Synthesis of a dendritic (soluble) hexanaphthylbenzene derivative is described in which the six naphthyl groups are connected to the central benzene ring in a propeller-shaped arrangement. Observation of multiple oxidation waves in its cyclic voltammogram as well as an intense charge-resonance transition (extending beyond 1600 nm) in its cation radical, generated by laser-flash photolysis using photoexcited chloranil as an oxidant, suggests that a single hole is mobilized via electron transfer (or hopping) over six identical (circularly arrayed) redox centers.
