A remarkably simple synthesis of [7]circulene 1 via an ethano‐bridged hexahelicene intermediate is described. Cyclic voltammetry reveals that 1 is easier to oxidize and reduce than coronene. The results of ab initio calculations for coronene, 1 , and its radical ions are consistent with the experimental findings.
