• ; hybrid organic–inorganic interface; mesoporous materials; nanostructured materials; polyion complex micelles; polyion electrostatic complexation; Introduction Due to their unique physicochemical properties originating from their uniform pore size and periodically arranged network at the mesoscale

• how a simple synthesis parameter, such as the pH of the reaction medium, which governs not only the extent of the polyion electrostatic complexation but also the silica condensation rate, influences the macrophase separation of the hybrid material and the nature of the mesostructures which are
