Photocatalytic decomposition of the pentacene ultrathin film grown on the TiO2 -terminated SrTiO3(001) single crystal substrate is studied. There are two kinds of pentacene on the SrTiO3: One is forming the crystal island as observed by atomic force microscope (AFM), the other is the precursor state adsorbed on the substrate. The latter is photochemically more reactive than the former. The pentacene molecule is released from the crystal island even at a low temperature such as 373 K due to its chemical nature of the van der Waals molecule.
