A rotaxane has been used as a linker in the manufacture of a metal organic framework
A rotaxane has been used as a linker in the manufacture of a metal organic framework (MOF) to give a rigid structure with a rotating macrocyclic ring within it. Writing in Nature Chemistry (DOI: 10.1038/nchem.1354), Stephen Loeb and colleagues from the University of Windsor, Canada, created the MOF and showed that the macrocycle can freely and rapidly rotate using 2H and 13C NMR.
The results suggest a way forward for solid state molecular switches and machines based on interlocked and mechanically constrained molecules like these MOFs.
