Methylviologen (1,1′-dimethyl-4,4′dipyridinium ion, MV2+) has been intercalated into the interlayer space of layered potassium titanoniobate (KTiNbO5) by a method involving the displacement of guest molecules using a n-hexylammonium titanoniobate (HeNH3+-TiNbO5) intercalation compound. The methylviologen titanoniobate (MV2+-TiNbO5) intercalation compound was characterized using SEM, TEM, XRD, IR and elemental analysis. The photochemical and electrochemical behaviors of the MV2+-TiNbO5 hybrid thin film were investigated. The photo excitation of oxygen-present MV2+-TiNbO5 thin film with UV light indicated the electron transfer from the titanoniobate layer to MV2+ to form MV+ radical cation. The cyclic voltammogram of the MV2+-TiNbO5 hybrid thin film exhibited two consecutive electron-transfer steps.
