Supramolecular organization of crown- and phosphoryl-containing magnesium and zinc phthalocyaninates in solutions of synthetic and natural surfactants

The behavior of crown- and phosphoryl-containing magnesium and zinc phthalocyaninates in solutions of synthetic and natural surfactants is studied. In a phosphate buffer (рН 7.4), zinc phthalocyaninate bearing oxy(pentyloxy)phosphoryl groups in peripheral substituents of the macrocycle is in aggregated state. According to absorption and fluorescence spectroscopy data, adding oppositely charged synthetic and natural surfactants leads to monomerization of this compound. The degree of monomerization of magnesium octa[(4´-benzo-15-crown-5)oxy]-phthalocyaninate in a microheterogeneous medium is affected by the concentration of sodium cholate and ionic strength. Fluorescence-active supramolecular gels based on sodium deoxycholate were prepared using phosphoryl-containing zinc phthalocyaninate.
