9,10 Anthraquinone thin films deposited under vacuum were investigated by IR absorption, X-ray diffraction and electron spectroscopy for chemical analysis (ESCA), scanning electron microscopy and optical absorption. It was found that crystallized 9,10 anthraquinone thin films are obtained for any kind of substrate after appropriate annealing. The c axis orientation of the monoclinic crystallites is essentially perpendicular to the plane of the substrate.The binding energies deduced from the ESCA lines and the frequencies of the IR absorption bands were found to be in good agreement with the powder reference. Optical absorption may be associated with a gap of about 3.25 eV.
