Thermal heating of the substance powder results in rather good evaporation. Smooth and glasslike homogeneous thin film with a metallic lustre has been obtained. The absorption spectrum of the film with a maximum at 680 nm is strongly broadened. The additional sulfur containing groups are bended forming a stool like structure. Phthalocyanine skeleton and the nearest not bended sulfur containing ring is involved into longwave transition. HOMO and LUMO are at -5.14 and -3.10 eV correspondingly. Vertical ionization potential of free molecule is 5.99 eV and adiabatic one is 5.90 eV. The dipole moment of this molecule is 4.85 D. The predominance of doped conductivity confirms the amorphism of the vacuum deposited film. The mechanism of conductivity was found to be hopping.}, number={21–22}, journal={Synthetic Metals}, publisher={Elsevier S.A.}, author={Kukhta, A. V. and Kolesnik, E. E. and Kukhta, I.
