Firmly tied : A four‐fold rotaxane was prepared from a porphyrin unit with four alkylammonium chains and a phthalocyanine unit with four peripheral crown ethers. In a dinuclear Cu 2+ complex of the four‐fold rotaxane, the Cu 2+ –porphyrin and the Cu 2+ –phthalocyanine moieties were stacked efficiently on one another to afford spin–spin communication. The spin states were switched reversibly (see picture).
