Three recognition sites —a bipyridinium unit and two secondary dibenzylammonium centers—within the tetracation 1 can be differentiated by two simple macrocyclic receptors, bis‐ para ‐phenylene[34]crown‐10 ( BPP34C10 ) and dibenzo[24]crown‐8 ( DB24C8 ). Strict self‐assembly processes under thermodynamic control yielded either [( DB24C8 ) 2 · BPP34C10·1 ] in a selective manner or the pseudopolyrotaxane [( BPP34C10 ) 2 · 1 ] n .
