The review is concerned with studies on peculiar features of supramolecular organization of phthalocyanines (Pc) bearing complex-forming substituents (15-crown-5, 2-oxyphenylphosphonic acid residues) in organized aqueous microheterogeneous media based on cationic and anionic surfactants, bile salts (BS) including sodium deoxycholate (SDC), as well as polyelectrolytes and amphiphilic polymers including a phosphate buff er (рН 7.4). Organized, SDC-based fl uorescence-active phthalocyanine-containing hydrogels obtained for the fi rst time are also considered. In vitro accumulation and localization of Pc in human cervical adenocarcinoma cells, HeLa, as well as the photochemical and sensitizing properties of Pc including light cytotoxicity and photoinduced generation of reactive oxygen species were demonstrated taking octa-crown-substituted magnesium phthalocyaninate as an example.
