Abstract
The surface morphology of tetraphenylporphyrin thin polycrystalline films – H2TPP and ZnTPP obtained by vacuum condensation under quasi-equilibrium conditions is analyzed by sc. The use of analytical methods for processing images of the organic films surface obtained by standard methods, allows to identify not only qualitative, but also quantitative characteristics of the polycrystalline films structure: the average grain size, grain size distribution, the presence of texture and characteristic of crystallites orientations. It is shown that free based H2TPP tetraphenylporphyrin films have a more pronounced texture and a larger crystallite size than ZnTPP, which is due to the peculiarities of self-organization of molecules, if condensation occurs under the same conditions. The applicability of this method of image analysis for obtaining information about the structure and morphology of the surface of thin organic films during vacuum condensation is shown.
