PHOTO-ACTIVE AND REDOX-ACTIVE [2]ROTAXANES AND [2]CATENANES

One cornerstone of supramolecular science is research into the manufac ture and physicochemical properties of [2]rotaxanes and [2]catenanes. Recent synthetic improvements have opened up the opportunity of buildi ng into the molecular framework of rotaxanes/catenanes subunits which can be stimulated by photons or redox changes. Accordingly, aspects of the chemistry of rotaxanes and catenanes deemed photoactive and redox active are discussed within this review.
