Photochemical processes, such as photolithography and photocurable resin process, have been attracting much attention owing to their enormous range of practical and industrial applications. Herein, we report the novel photofunctional materials that we have recently developed. One of these materials shows photochemically reversible liquefaction and solidification based on the photoisomerization of the azobenzene arms of the molecular backbone in the solid state. Another material, which is a photo-functional gel, shows a rapid and site-selective photocuring on the damaged surface. We believe that these materials would be promising candidates for many useful applications.
