In this work, structural features and optical properties of hexadecafluorosubstituted vanadyl phthalocyanine (VOPcF16) films deposited by Organic Molecular Beam Deposition (OMBD) technique have been investigated. Thin films of VOPcF16 were characterised by ellipsometry, optical absorption and vibrational (IR and Raman) spectroscopy. VOPcF16 films deposited onto silicon and quartz substrates held at room temperature are well organized and characterised by a predominantly co-facial parallel arrangement of molecules vertical to the surface. Thermal treatment of these films at 220 °C leads to the transition from one phase to another and formation of the polycrystalline VOPcF16 films with randomly distributed crystallites on the substrate surface.
