Synthesis of new coordination compounds of 3d- and 4-f metals, hybrid and polymer systems based on them for the creation of new composite and functional materials based on various ligand systems: - β-diketones, as precursors of complex oxide systems and monomers in polymerization and copolymerization reactions (luminescent materials and catalysts); - carboxylates, polydentants of the system for the creation of biologically active compositions and bis-chelating, as additional ligands in the study of multi-ligand complexation (biological action, catalytic activity); - curcumin and their derivatives (antioxidants, antivirals, antimicrobials, luminescent markers)

 The work focuses on the development of new coordination compounds of 3d- and 4f-metals based on β-diketonate, carboxylate, and curcumin-based ligands. Effective methods for the synthesis of coordination compounds and studies of their physicochemical properties have been developed. Hybrid and polymeric materials with predicted functional characteristics were obtained based on these compounds. The research involved the synthesis and investigation of the properties of novel coordination compounds of 3d- and 4f-metals with polydentate O,N,P-containing ligands. Special attention was given to the creation of hybrid nanomaterials for sensors, lasers, optical converters, and amplifiers. It has been demonstrated that the modification of organo-inorganic matrices with lanthanide complexes enhances the thermal stability and luminescent properties of the materials. Spectral studies revealed the possibility of targeted control of emission in various spectral ranges. The spectral and luminescent properties of the synthesized compounds, particularly EuTb-diketonates, were studied, showing tunable co-luminescence in red and green spectral ranges, which is promising for the development of RGB LEDs and laser systems. Using self-assembly methods, heteroligand complexes of 3d-metals (Co, Ni, Cu) and lanthanides (Nd, La) were synthesized for the first time, offering potential applications in photonics, optoelectronics, and catalysis. Сurcuminates of zinc and copper exhibited high antibacterial activity and significant antioxidant effects. Hybrid materials based on aluminosilicates and silsesquioxanes demonstrated high thermal stability and improved catalytic properties. The study introduces innovative approaches to the controlled synthesis of coordination compounds with advanced functional characteristics, which can be utilized in modern technology, medicine, and environment applications, as well as for addressing critical challenges in the defense industry and the economy of Ukraine.
