Titania mesoporous films with an accessible cubic mesostructure were deposited on a conductive electrode. Organic groups (phenyl, hexadecyl, glycerol) were added to the pore surface by post-grafting. The transport properties of electrochemical probes such as ferrocyanide or ferrocenedimethanol within the pore system depend on the grafted function; in extreme cases, blocking and selective solubility effects are observed.
