Photocontrolled TranslationaS Motion of a Microscale Solid Object on Azobenzene-Doped Liquid-Crystalline Films

摘要

Several attempts to control linear or rotary motion of micro-or nanoscale materials on surfaces,in which the ultimate goal is the development of synthetic micro-or nanomachines,have been reported.The light-driven rotary motion of a micro-scale object by a molecular motor embedded in a liquid-crystalline matrix has been reported by Feringa and coworkers.Some research groups have reported the photo-controlled translational motion of a liquid droplet,which is located on a glass surface modified with a photoswitchable molecule,by generating a surface energy gradient.
