Reversible machano‐ and thermochromic behavior are‐features of the title bis(tricyclic) olefin. These characteristics are a consequence of the different proper ties of the interconvertible folded and twisted confomers. Despite the severe molecular deformation the conductive charge‐transfer complexes and stable salts of the radical anion could be isolated due to their strong electron affinity.
