Copper (CuPc) and vanadyl-phthalocyanine (VOPc) thin films were prepared by a vapor deposition method on a Au(111) substrate. The orientations and morphologies of the copper and vanadyl-phthalocyanine thin films were investigated with ultraviolet/visible (UV/vis) spectra measured by UV/vis spectroscopy and with X-ray diffraction (XRD) profiles obtained by X-ray diffractometry. VOPc molecules deposited on the Au(111) substrate at 150 °C were parallel to the substrate and grew in pseudoepitaxy at a thickness of 50 nm. Conversely, CuPc molecules evaporated on the Au(111) substrate under the same conditions as VOPc molecules were in the $\alpha$-type phase and perpendicular to the substrate. This indicates that the CuPc molecules are not trapped at the trapping sites on the Au(111) substrate.
