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 structures 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.

Brief Biography

Steve Loeb is the Canada Research Chair in Supramolecular Chemistry and Functional Materials in the Department of Chemistry and Biochemistry at the University of Windsor. He completed his PhD at the University of Western Ontario under the supervision of Chris Willis and was a postdoctoral fellow with Martin Cowie at the University of Alberta. He was elected a Fellow of the Chemical Institute of Canada in 1997, a Fellow of the Royal Society for Chemistry in 2007 and was the 2012 recipient of the Canadian Society for Chemistry’s Rio Tinto Alcan Award for outstanding achievement in Inorganic Chemistry. He has made significant contributions to the design and synthesis of interlocked molecules (rotaxanes and molecular shuttles) and recently pioneered their incorporation into metal-organic framework materials.
