The CpCo‐shuffle : {CpCo} complexes of linear [3]‐ and [5]phenylene undergo a light‐induced haptotropic migration from a more strongly bound cyclobutadiene moiety to a less strongly bound (see scheme). The shift is thermally reversible and proceeds along the periphery of the intervening arene rings. As such, the systems constitute photo–thermal storage systems, as well the first examples of cyclobutadiene‐to‐cyclobutadiene haptotropism.
