The microscopic structures of two nano-structured inorganic films, one based on titania nanosheets (TNS) and the other on mesoporous silica (MPS), were investigated. The clear stacking structure of the TNS and MPS films were observed by the XRD, SEM, and TEM analyses. The selective adsorption of the porphyrin derivatives into the MPS nano-cavities and viologens into the TNS nano-layers was also investigated by absorption and energy-dispersive spectroscopy (EDS).
