“…For permanent integration of spiropyran onto surfaces, chemical modification of both the SiO 2 surface and spiropyran is essential. A prevalent method is the use of silane chemistry to attach amine groups to the surface, which can react with spiropyran molecules that have been functionalized with hydroxyl, carboxyl, , or other reactive groups. ,− Moreover, advanced modification techniques have improved the integration of spiropyran into silica-based materials. Spiropyrans have been embedded as pendant groups within monomers, such as methyl methacrylate or norbornene, which are then polymerized onto modified SiO 2 surfaces.…”

The ability to control the function and structure of some promising nanosystems using an external stimulus is attractive research to develop programmable and reconfigurable intelligent nanomaterials. The focal point of this review is the silicon-based nanoporous materials, and particularly the mesoporous silica materials (MSMs) class (pore size: 2–50 nm), due to their important intrinsic properties, such as high surface area, highly ordered nanostructure, narrow pore size distribution, various dimensions (one-dimensional, two-dimensional, and three-dimensional), and easily functionable. One of the most essential organic components that can be incorporated in MSMs is organic photochromic molecules (OPMs), such as azobenzene, stilbene, dithienylethenes, and spiropyrans. OPMs can be incorporated into MSMs, to form photochromic mesoporous organosilica materials (PMOMs), in two different ways: physical (non-covalent immobilization) or chemical (covalent immobilization) binding. PMOMs are considered smart nanomaterials because they have the ability to undergo reversible changes in the solid state when exposed to an external electromagnetic radiation. PMOMs have been the subject of many research studies during the last decade due to their potential applications, especially as chemosensors. This review discusses the main families of OPMs, their incorporation into MSMs using different methods, and the applications of some PMOMs as chemosensors.
