The stability of naturally occurring dyes can be improved by incorporation into various inorganic host materials. In this study, we try to insert hydrophobic plant-derived dye between the layers of hydrotalcite. Prior to the complexation with the hydrophobic dye, the hydrotalcite is modified with anionic surfactant to make the interlayer space more hydrophobic. By simply mixing the powdery dye and the organo-modified hydrotalcite, the dye molecules can be incorporated into the interlayer of the hydrotalcite by a hydrophobic interaction. The intercalated dye shows an improved stability against visible light irradiation. On the other hand, rather hydrophilic dye shows less effect on the stability improvement by the complexation, although it has a similar molecular skeleton as the hydrophobic dye.
