Abstract— Using the nitrile method of heating 4,5-di(2,4,5-trichlorophenoxy)phthalonitrile with magnesium and zinc acetates, and also aluminum and erbium chloride, at 200–240°C, metal complexes of the corresponding substituted phthalocyanines with magnesium, zinc, aluminum, and erbium, were synthesized. The ability of the obtained metal-phthalocyanines to dissolve in concentrated sulfuric acid, dimethylformamide, and chloroform was studied. The effect of the complexing metal on the position of the Q-band of the synthesized compounds was found.

Keywords: 2,4,5-trichlorophenol, phthalonitrile, phthalocyanine, electronic absorption spectra
