Azobenzene derivative, azobenzene crosslinker, phenylbenzoate derivative and hydroquinone crosslinker with vinyl groups were synthesized to fabricate the crosslinked liquid-crystalline polymer films. Undirectionally aligned crosslinked azobenzene liquid-crystalline polymer films with a polysiloxane backbone were prepared by hydrosilylation reaction. Two-dimensional surface labeled gratings were recorded in surface of the film with a photomask. A probe beam at 633 nm was incident to the film, and surface deformation of the film was evaluated by an external stress or ultraviolet irradiation using a light diffraction. In addition, effect of position and behavior of front and back surfaces in the film on the deformation has been investigated.
