Photoswitch, or photo-electric switch, is a sensor that detects the presence of light or a change in its intensity. Photoswitches are one type of molecular machines, a class of molecules that can be switched between at least two distinct thermodynamically stable forms by the application of an external stimulus. The development of such devices is crucial in the framework of nanotechnology; nowadays, photoswitches are applied in a variety of places from scientific applications to residential light timers. Organic compounds have been deployed as photoswitches and a popular example of it is azobenzene.
