A supramolecular homodimer is formed in solution and in the solid state by a self‐complementary [2]catenane incorporating a 1,5‐dioxynaphthalene‐based macrocyclic polyether interlocked with a bipyridinium‐based tetracationic cyclophane (shown schematically). This unique example of self‐recognition is the result of a combination of cooperative π⋅⋅⋅π and C−H⋅⋅⋅π interactions.
