Photonic crystals having a three dimensional periodic structure have attracted much attention from both fundamental and practical points of view, because of their unique properties in controlling the propagation of light. One of the promising techniques for fabricating three-dimensional photonic crystals is preparation of self-assembled colloidal crystal. In this study, we prepared two kinds of colloidal crystalline systems having photochemically patterning ability and investigated their patterning properties: one is colloidal spheres containing cinnamic moieties, and the other is silica colloidal crystals containing photocurable resin. The photochemically patterning ability was identified for both systems.
