Molecular matter for specific functions Physical Chemistry

Mesostructured silica thin films and particles prepared by surfactant‐templated sol–gel techniques are highly versatile substrates for the formation of functional materials. The ability to deliberately place molecules possessing desired activities in specific spatially separated regions of the nanostructure is an important feature of these materials. A facile and universal approach is reported for the preparation of silica particles of various mesostructures based on the self‐assembly of amphiphilic precursor polymers in water and subsequent condensation.

Indeed, mesoporous silica carriers can be loaded with curcumin, which can afterwards be released in a sustained way, so enhancing its pharmacological effects [ 10 ].

The CTAB/Pluronic mole ratio was varied from 0.0 to 10.0 to optimize the reaction conditions and to elucidate the ef-fect of CTAB in the formation of the mesostructured silica particles. Mesostructured photochromic pigments were synthesised by incorporating photochromic dyes in the organic domains of the surfactant templated inorganic/organic mesostructured silica particles. The pigments were produced using a one-pot synthesis method employing an aerosol reactor, allowing control over both the internal mesostructure and the dye content. of mesostructured functionalized silicaparticles at lower concentration into the PES matrix is proposed in this work to explore two effects: po-rous ordering and silica functionalization.
