ERBIUM AND SANDWICH-TYPE LUTETIUM COMPLEXES CONTAINING FRAGMENTS OF TETRAANTHRACHINOPORPHIRAZINE AND SUBSTITUTED PHTHALOCYANINES

The present work relates to the synthesis and spectral properties of erbium sandwich type metal complexes containing tetraanthraquinoporphyrazine as well phthalocyanine fragments. By reacting tetraanthrachinoporphirazine (lutetium) acetate with excess phthalonitrile, 4-chloro, 4-bromophthalonitrile unsubstituted sandwich-type an unsymmetrical structure were obtained. compounds extracted from reaction mixture a suitable organic solvent (DMF or toluene) purified by prolonged extraction impurities acetone in Soxlet apparatus. Final purification was carried out column chromatography. obtained are green solids having solubility DMSO, DMF, concentrated sulfuric acid. composition confirmed elemental analysis, IR electron spectroscopy. Influence chemical new "sandwich" on their possible applications has been investigated. In particular, when analyzing absorption spectra, it found that metal, nature substituents tetraanthraquinone moiety replacement hydrogen atoms halogen slightly affect position maxima. Studies have coloristic synthesized organosoluble lutetium. exhibit pigments dyes for polymeric materials such polystyrene polyethylene. temperature parameters thermal oxidative degradation determined phthalocyanines high resistance degradation.
