A few research group reports formation of ordered structures of colloidal particles due to topological defects in a nematic liquid crystal. In this paper, we describe the photochemical phase transition of a nematic liquid crystal by the photoisomerization of azobenzene dyes, focusing especially on the dynamical effect of the trans–cis–trans photoisomerization cycle of a push-pull azobenzene dye. Then, we discuss the effects of light irradiation on the motion of small objects dispersed in the nematic and smectic liquid crystals contatining a push-pull azobenzene dye, and successfully manipulate those objects by pushing, trapping and dragging them.
