We present the synthesis of a macrocyclic ruthenium(II) complex that combines the versatile photophysics and supramolecular chemistry of biimidazole ruthenium(II) chromophores with a macrocyclic geometry that allows for its introduction into mechanically interlocked frameworks. Structural information on the core framework was gained from a solid‐state structure. The new supramolecular building block shows that the principal photophysics of the ruthenium chromophore, that is, the cation‐driven light‐switch effect, are retained during the formation of the macrocycle.
