The authors discuss the molecular motion of surface-immobilized molecular machines. The cyclodextrin necklace and double-decker phthalocyanine complexes were used as examples of the translational motion and rotational motion of molecules, respectively. For the translational motion of cyclodextrins (CyDs), the relationship between the intermolecular interaction of CyDs composed of the cyclodextrin necklace and the interaction between CyDs and substrates was an important factor in determining the molecular mobility. For the rotational motion of double-decker phthalocyanine complexes, the combination of molecules composed of double-deckers as well as the free space around a top ligand was important issues in controlling the molecular motion of immobilized double-decker complexes on solid surfaces.
