Light can act on materials without contact

so it is an ideal trigger mechanism and can selectively

non-estructively and remotely activate external stimuli. As a kind of aromatic azo compounds

azobenzene compounds can produce isomeric effects under different light conditions

and this kind of aromatic azo compounds have reversible isomers. The configuration changes based on different wavelengths can make the azobenzene compounds produce micro and macro movements. Based on this macroscopic mechanical deformation and reversible mechanical drive

this kind of photomorphic compounds can be used to make photomechanical and other photomechanical products. Meanwhile

azobenzene derivatives have good properties in drug release and super wetting materials.
