    In this work, the results of mass spectrometric studies of the composition of gaseous phase under solid compounds of tetra-tert-butyl substituted phthalocyanines MPc(t-Bu)(4), with M = Cu(II), 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-butyl-phthalocyanines 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 investigation of structural features of MPc(t-Bu)(4) films was carried out using UV-vis spectral and XRD data. (C) 2010 Elsevier B.V. All rights reserved.
