A Photoswitchable [2]Rotaxane Array on Graphene Oxide

Abstract

Switch! A photoswitchable α-cyclodextrin-based [2]rotaxane array on graphene oxide (GO) was prepared. The α-cyclodextrin ring in the [2]rotaxane on the GO surface can move back and forth along the dumbbell component driven by trans–cis isomerization of the azobenzene unit. This system has potential applications in the development of GO-based photoswitches. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
