Artificial molecular switches and machines based on the relative motion of the components of mechanically interlocked molecules (MIMs) are most often devices that operate in solution where they are randomly dispersed and their motion incoherent. In order to create ultra-dense molecular-based memory or control electronic properties of materials at the molecular level, these tiny devices need to be organized in a predictable and orderly manner. One way to achieve a higher level of molecular organization and coherency would be to precisely place the “soft” dynamic molecular components that undergo motion (e.g. rotation or translation) into the pores of metal organic framework (MOF) materials In this way, the “soft” MIM would be clearly separated from the “hard” structural skeleton of the MOF that holds it in place. The small size of a MIM unit (~1 nm3) and the regularity of a MOF framework would allow for an incredibly high density of dynamic components in a material. This presentation will describe our newest MOF materials containing MIM linkers capable of rotational and translational motion.
