Resumen:
Mesoporous thin films containing organic functions behave like selective membranes.Titania mesoporous films with an accessible cubic mesostructure were deposited on aconductive electrode. Organic groups (phenyl, hexadecyl, glycerol) were added to the poresurface by post-grafting. The transport properties of electrochemical probes such asferrocyanide or ferrocenedimethanol within the pore system depend on the grafted function;in extreme cases, blocking and selective solubility effects are observed.
