Реферат: In this paper, the temperature dependence of the saturated vapor pressure of fluorosubstituted phthalocyanines with substituents in non-peripheral positions of the macroring, viz. MPcF4-np, M=Cu, Fe, Co, VO, was investigated by the Knudsen effusion method with mass spectrometric registration of the gaseous phase composition. The standard thermodynamic parameters ΔH°T and ΔS°T of the sublimation process of these compounds were determined. The results were compared with the vapor pressure of the corresponding MPcF4-p analogs bearing F-substituents in the peripheral positions. It was shown that the volatility decreased in the order of VOPcF4-np>CoPcF4-np ~ CuPcF4-np ~ FePcF4-np>ZnPcF4-np, which correlated with the increase in their crystal lattice energy in the same order. The volatility of most MPcF4-np (M=Cu, Zn, Co, VO) was lower than that of MPcF4-p. The results were analyzed from the point of view of crystal packing and intermolecular interactions in the crystal.
