In this work, the results of mass spectrometric studies of the composition of gaseous phase under solid compounds of MPc(t-Bu)4, with M=Cu, VO are presented. The vapour pressure of this phthalocyanine is determined as a function of temperature by the Knudsen effusion method, in which the rate of effusion of the equilibrium vapour through a small orifice is measured. It is shown that these tetra-tert-butylphthalocyanines exhibit higher volatility than their unsubstituted analogues. Such data are needed in order to improve the operating conditions of the growth of thin films by OMBD. The comparison of volatility with un-substituted phthalocyanines was carried out on the basis of UV-VIS spectral and XRD data.
