Hybrid non-silica mesoporous thin films

Large-pore TiO2 and ZrO2 mesoporous films with 2D-Hex or cubic mesostructures were prepared by dip-coating. Organic bifunctional molecules presenting an organic function and a complexing grafting group (phosphate, carboxylate) were explored as surface modifiers. The incorporation of these functions...
