摘要：
The basic physicochemical properties and molecular structure of bis-(thrimethylsiloxy). phthalocyaninato silicon [SiPc(OSiMe3)(2)] are investigated. The temperature of melting of this complex was measured by the DSC method in the temperature interval 20-520 degrees C (T-m = 497 degrees C). Thermogravimetric analysis data showed mass loss occurs in the temperature range 275 - 500 degrees C. The mass loss in this temperature range is 96 %. Mass spectrometric studies of the composition of the gaseous phase of [SiPc(OSiMe3)(2)] was performed in the temperature range up to 450 degrees C. It was found that the complex is sublimated in monomeric form. The vapor pressure of the compound was determined as a function of temperature by the Knudsen effusion method. Based on the data obtained, the thermodynamic parameters of the sublimation process are calculated. The X-ray diffraction study revealed that molecular geometric parameters of [SiPc(OSiMe3)(2)] are varied slightly upon changing of temperature. The photovoltaic properties of [SiPc(OSiMe3)(2)] studied with heterojunction solar cell of configuration of ITO/complex/C60/Bphen/Al. The operating characteristics of the cell turned out comparable with the characteristics of earlier designed analogues devices based on phthalocyanine complexes of Cu, Zn and Sn.
