Abstract
AbstractWe report a new supramolecular rotor (1), in which a lanthanum(III) bis(porphyrinate)s double‐decker (LaDD) bears two porphyrinatorhodium(III)‐based rotors whose planes aresituated orthogonally to one another. In [D2]dichloromethane, 1H NMR spectral results indicated that rotational information was transmitted from the LaDD rotor to two porphyrinatorhodium(III)‐based rotors through mechanical interaction of the teeth of the rotors. Mechanical interaction was achieved among the multiple rotors in 1 even after switching the rotational activity of the LaDD rotor by using [D5]pyridine. The spatial arrangement of the two porphyrinatorhodium(III)‐based rotors is a critical factor in maintaining mechanical interaction between multiple molecular rotors when changing the dynamic properties of one rotor.
