Based on the principle of "layer-by-layer method", which is overcompensation of each layer charge, intercalation of cationic or basic polyelectrolytes into anionic layered oxides was investigated, yielding a novel layered host material with the ability to encapsulate anionic substances. By utilizing the anion acceptability of the obtained polyelectrolyte/layered oxide composites, encapsulation of an acidic blue dye and gold nanoparticles was succeeded. While the focus in this work has been to prepare colorants that might be of interest in applications such as pigments and cosmetics, I note that the new techniques shown here will create a new potential way for intercalation chemistry and contribute to the evolution of new functional hybrid materials for a rich variety of applications including pigment, cosmetics, catalysis, medicine, optics, and environment in the future.
