Resumen:
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
into the mesoporous network was monitored by crossed FT-IR
and EDS techniques. Leaching experiments in different conditions
were performed to assess the anchoring of the grafted
groups. While phosphate or phosphonate groups are strongly
grafted, carboxylate functions can be released in a pH-dependent
way.2 and ZrO2 mesoporous films with 2D-Hex or
