The stabilities of organic dyes have been controlled by host-guest complexation and the hybrids have been regarded as novel photofunctional materials. In the present review, the dyes encapsulated in smectites and layered double hydroxides are summarized from the viewpoints of the dye stabilization and possible mechanisms for the stabilization toward decolorization are discussed. In addition, the stabilization of photochemically formed isomer of a photochromic spiropyran, by the interactions with smectite is also presented.
