Purpose of investigation - development of optimal methods for the synthesis of luminescent lanthanide polynuclear systems based on crown- and porphyrin-calix[4]arenes; studying of s- and d-metals nature influence on the spectral-luminescent properties of heteronuclear systems. The analysis of structural factors and microenvironment influence on the spectral properties of fluorescent systems was carried out. It was shown that in ytterbium complexes with porphyrin-calix[4]arene luminescence are observed both in the visible and infrared regions of the spectrum. The study of the crown calix[4]arenes and their complexes with lanthanides in micellar solutions of surfactants and water-organic media provides information about the immediate surroundings of luminescent centers, mechanisms of sensitization or quenching of their luminescence, which allows to get more details about structure and properties of organized molecular systems.
