The behavior of magnesium octa[(4’-benzo-15-crown-5)-oxy]phthalocyaninate (Mgcr₈Pc) in aqueous solutions of polyelectrolytes as well as their mixtures with anionic surfactants such as sodium dodecyl sulfate and biocompatible sodium deoxycholate has been studied. A synergistic effect of sodium deoxycholate and sodium polystyrene sulfonate promotes Mgcr₈Pc monomerization in the aqueous environment. For the first time, it was shown that fluorescent hydrogel was formed in the Mgcr₈Pc/sodium deoxycholate/lysine hydrochloride system. In all cases, the existence of Mgcr₈Pc as a micelle-bound monomer has been confirmed by the increase of the emission intensity, since aggregates and H-dimers do not fluoresce.
