A Redox-Active Bistable Molecular Switch Mounted inside a Metal-Organic Framework
We describe the incorporation of a bistable mechanically interlocked molecule (MIM) into a robust Zr-based metal organic framework (MOF), NU-1000, by employing a post-synthetic functionalization protocol On average, close to two bistable [2]catenanes can be incorporated per repeating unit of the hexagonal channels of NU-1000. The reversible redox-switching of the bistable [2]catenanes is retained inside the MOF, as evidenced by solid-state UV-vis-NIR reflectance spectroscopy and cyclic voltammetry. This research demonstrates that bistable MIMs are capable of exhibiting robust dynamics inside the nanopores of a MOF;
