A reversible mechanical control of the mobility of the interlocked rings is possible in photoswitchable catenanes like 1 . Furthermore, the crown ether guest influences the thermal isomerization of the azobenzene host: the catenane 1 isomerizes ten times faster than the unoccupied host macrocycle from the ( Z ) to the ( E ) configuration.
