A DYNAMIC METAL-ORGANIC ROTAXANE FRAMEWORK

摘要

We have placed a mechanically interlocked molecule (MIM) into the pores of a metal organic framework (MOF) designated as UWDM-1 (University of Windsor Dynamic Material).UWDM-1 is constructed from a [2]rotaxane ligand in which the axle contributes to the rigid MOF skeleton, while the macrocycle functions as the soft dynamic component, capable of undergoing thermally controlled rapid rotation inside the material. UWDM-1 is characterized by single crystal and variable temperature powder X-ray diffraction, while the motion of the macrocyclic wheels is characterized by deuterium solid-state NMR. This poster will describe the synthesis and characterization of UWDM-1 (see Figure 4).
