Vapor Pressure of Some Metal Phthalocyanines

The temperature dependences of saturated vapor pressures of hexadecafluorinated zinc and vanadyl phthalocyanines (MPcF16, M = Zn, VO) and their unsubstituted analogues were studied by the Knudsen effusion method. The temperature dependences of saturated vapor pressures were used to calculate the thermodynamic parameters of vaporization of phthalocyanines.
