Mentions: At a given temperature, the macrocycleof a rotaxane distributes itself among the existing stations accordingto the binding affinity of each. Perturbation of the binding energiesof any of the stations results in the redistribution of the macrocycletoward a new equilibrium state, as driven by thermal motion. Changingthe position of the macrocycle in a well-determined way is possible,by making the binding affinity of the less occupied station more favorable(Figure 25, transformationof station B to B′),14 or by destabilizingthe interaction between the most occupied station and the macrocycle(Figure 25, transformationof station A to A′). Stimuli responsive modification of themacrocycle can also drive such shuttling processes. Redox, pH, light,and microenvironment (temperature, solvent, etc.) switches are commonlyused to control translational movement in rotaxane architectures,and will be discussed in the following sections.
