Abstract
Crown-containing Pc Mg[(B15C5O)8Pc], Mg[(B15C5O)4Pc], and Mg[(15C5)4Pc] are in the monomolecular state in solutions of synthetic anionic surfactants: sodium dodecylsulfate and sodium dodecylbenzenesulfonate. In micellar solutions of bile-acid salts, molecular organization of crown-substituted Pc with different methods of introduction of crown groups into the macrocycle and their different numbers changes their state from predominantly monomeric for Mg[(B15C5O)8Pc] in the presence of NaCl to the aggregated one in the case of Mg[(15C5)4Pc)]. Magnesium phthalocyaninate with annulated (15-crown-5)-fragments, Mg[(15C5)4Pc], is characterized by the highest sensitivity to the structure of the micelle-forming biocompatible surfactant.
