Abstract:Fragrances are widely used in our daily life and have made great contributions to creating a clean and fresh healthy air environment. However, the rapid volatilization severely influences their storage, application and quality. Therefore, it is necessary and urgent to develop approaches to controllably release the odorants as demanded. In this study, photo-driven mesoporous silica nanospheres loaded with sandela 803 was designed, prepared and named as S803@MS-S. S803@MS-S possessed ordered mesoporous, large specific surface area and pore volume. After adsorption of sandela 803, the S803@MS-S was added into wallpaper to prepare fragrant wallpaper S803@MS-S-W. And this wallpaper exhibited excellent sustained and controlled release performances stimulated by light.
Keywords:Mesoporous silica nanospheres  Sandela 803  Photo-driven release  Wallpaper  Azobenzene derivatives
