Poly(ethylene glycol) containing surfactant molecules were modified with titanium alkoxides.

Solvent evaporation-induced self-assembly methods based on supramolecular organization of amphiphilic molecules in combination with sol-gel processing of condensable inorganic precursors result in porous thin films with a monomodal pore size distribution. By employing high speed spin coating for the film formation and high temperature (80 °C) drying and aging, we developed a synthesis procedure for mesostructured silica thin films that can reproducibly produce up to eight different pore morphologies, including a rhombohedral (R m), a centered rectangular (c2mm), two wormlike, two curved lamellar, and two lamellar structures. We report the self‐assembly and characterization of mesoporous silica thin films with a 3D ordered arrangement of isolated spherical pores. The preparation method was based on solvent‐evaporation induced self‐assembly (EISA), with MTES (CH 3 –Si(OCH 2 CH 3 ) 3 ) as the silica precursor and a polystyrene‐ block ‐poly(ethylene oxide) (PS‐ b ‐PEO) diblock copolymer as the structure‐directing agent.

Photo-conductivity studies were made on these films to know their Mixed metal oxide-doped mesostructured silica films have been prepared by a combination of a ligand-assisted templating (LAT) and solvent evaporation-induced self-assembly (EISA) approach using Abstract Mixed metal oxide-doped mesostructured silica films have been prepared by a combination of a ligand-assisted templating (LAT) and solvent evaporation-induced self-assembly (EISA) approach using metal alkoxides as precursors. To overcome the problem of the different hydrolysis and condensation rates of the various alkoxide precursors (silicon alkoxides and transition metal alkoxides Mesostructured silica-polymer films are a good host for laser dyes, such as Rh6G, because a large concentration of a dye can be incorporated without concentration quenching.
