Graphical Abstract

Can light drive a motor? Azobenzene-containing liquid-crystalline elastomers (LCEs) and their composite materials have the potential to show three-dimensional movement by light irradiation. With the LCE laminated films, a first light-driven plastic motor has been developed, which can convert light energy directly into a continuous rotation without the aid of batteries, electric wires, or gears.
