Professor Stossart's research interests are in chemistry beyond the molecule, which, combined with his interest in templation, has led to the template-directed synthesis, based on molecular recognition and self-assembly processes, of a wide range of mechanically interlocked molecules, bistable variants of which have found their way in the form of switches into molecular electronic devices and drug delivery systems. In terms of molecular structure, his research straddles the size regime from the mesomolecular scale all the way up to the nanoscopic, microscopic and macroscopic levels: it includes wholly synthetic polymers and metal-organic frameworks. He also embraces radical chemistry in both the supramolecular and mechanostereochemical domains.
