The spectral-luminescent properties of the synthesized compounds have been studied. The correlation between the composition, stability and properties of the complexes depending on the nature of unsaturated substituents in the beta-diketonate ring, the electronic structure of metal ions is established. It is shown that the best emission properties complexes and metal polymers of Eu (III) with phenyl and biphenyl substituents. New aliphatic and aromatic aminocarboxyphosphonic acids were synthesized for the first time (N,N-bis (phosphonomethyl) -2-aminopropionic acid, 6-phosphonopyridine-2-carboxylic and 6-phosphonopiperidine-2-carboxylic acids, 5-phosphonic phosphinoproline characteristics The processes of complex formation are investigated. Mono- and multiligand complexes of Co(II) and Cu(II) with rutin and glycine were analyzed. The influence of the ratio of L: M and pH of the medium on the structure was established. The luminescent and antimicrobial properties of the complexes have been studied. All compounds show high antibacterial activity. The optimal conditions for the synthesis of heterometallic multiligand complexes of 3d metals and lanthanides with acetylacetone, carboxylic acids and neutral ligand were determined. It is shown that the use of β-diketonate precursors can reduce the maximum synthesis temperature of complex oxides to 800 °C and heat treatment time to 3 hours, which can significantly reduce the duration and energy consumption of the synthesis. Deposition of LnxMyOn complex oxide structures on alumina granules was performed. Nanoclusters of complex metal oxides with a particle size of 25-50 nm are deposited on the surface of spherical Al2O3 particles. Product Description popup.authors Ivakha Nadiia B.
