Resumen:
Organic molecules have been incorporated into the pore system of mesoporous TiO2 and ZrO2 xerogels
and thin films. Surface-modifying functions include alkyl, aryl, amino, sulfonate, thiol, and polyol.
Phosphate, phosphonate, carboxylate, and polyphenol were used as grafting groups. The incorporation
of these functions into the mesoporous network (typically 2-8 ímol/m2) was monitored by crossing
FTIR and EDS. In particular, the cases of dihexadecyl phosphate, monododecyl phosphate, 3-nitrophthalic
acid, TIRON (disodium 1,2-dihydroxybenzene, 3,5-disulfonate), and thiol-bearing carboxylates are
discussed. Uptake experiments suggest that the pore structure plays a key role in the accessibility of the
pore system. Leaching experiments in different solvents and conditions were performed to assess the
anchoring of the grafted functions. This permits tailoring of the molecule grafting, from firmly anchored
functions to groups with controlled lability.
