Photoresponsive nanocomposite formed by self-assembly of an azobenzene-modified silane

Abstract

Organization of photoresponsive azobenzene ligands within a 3D porous framework imparts new molecular-level functionality. The trans ⇌cis conformation change of azobenzene ligands triggered by photoirradiation transduces photo energy into mechanical work, which can be used for opening and closing valves (see picture).
