Abstract

The work is devoted to the preparation of zinc complexes of tetra(4-octyloxyphenoxy)phthalocyanines, as well as its sulfonated derivatives and the study of their properties, primarily spectroscopic and luminescent. The compounds were synthesized and characterized by IR and electron spectroscopy, MALDI-TOF mass spectrometry and elemental analysis. Absorption spectra were obtained in the visible range in chloroform, DMF, water (for the sulfonated analogue). It was shown that in the studied concentration range the complexes exist in monomeric form. Sulfonated phthalocyaninates turned out to be aggregated only in an aqueous medium, which made it possible to study the fluorescent properties in an organic medium (namely, in DMSO). The introduction of a sulfonate groups was found to lead to quenching of fluorescence in comparison with an organo-soluble phthalocyaninate.
