SYNTHESIS AND RESEARCH OF SILICON-CONTAINING PHTHALOCYANINE

Abstract

The aim of this study is to synthesize, and study a new form of dye based on phthalocyanine, a silicon-containing phthalocyanine pigment used as a dye for dye-sensitive solar cells, which are currently third generation solar cells as one of the energy source alternatives. To achieve this goal, a silicon-containing phthalocyanine pigment containing urea, phthalic anhydride and sodium fluorosilicate was synthesized and studied. Based on the results of IR spectroscopy, the reaction of pigment formation is proposed and the data of scanning electron microscopy is presented. Its differential thermal analysis, photodynamic analysis and its relationship with inorganic and organic solvents were also analyzed. The optical density of the pigment was analyzed on a V-5000 spectrophotometer at wavelengths with a spectral with from 320 nm to 1000 nm. The study was carried out in 5% and 20% solutions of dimethylformamide. The absorption peaks showed good absorption at wavelengths from 400 to 500 nm. Derivatographic studies of the obtained pigment show that the main weight loss occurs in the range 110-482 °C, at which 18.25% of the basic weight, or 3.21 mg of weight, is lost, which means that the pigment is thermally stable.
