A radical interaction has been employed as the recognition motif in the template‐directed synthesis of a [2]rotaxane composed of cyclobis(paraquat‐ p ‐phenylene) and a viologen derivative. The ruthenium tris(bipyridine)/triethanolamine system is used as the electron‐transfer photocatalyst to generate the necessary radical cation components that result in the formation of an inclusion complex. A stoppering reaction follows to form the mechanical bond.
