There are numerous examples of how interlocked molecules can operate as rotors and switches in solution. However, in this medium the molecules are randomly dispersed and their motion is incoherent. The periodic nature of metal-organic frameworks (MOFs) allows a way to achieve a high level of molecular organization. This work will present the synthesis of MOFs containing dynamic [2]rotaxane molecules and characterization of the nature and rate of the dynamic processes by variable-temperature 13C and 2H solid-stare NMR.
