Ivakha N. Synthesis and properties of mono- and polymeric β-dicarbonyl complexes of Cu (II), Ni (II), Nd (III), Er (III), Yb (III).

Thesis is devoted to the synthesis and research of the properties of mono-, mixed-ligand, hetero-metallic complexes of Cu (II), Ni (II), Nd (III), Er (III) and Yb (III) with β-dicarbonyl ligands (2-methyl-5- phenylpentene-1-dione 3,5, allyl-3-oxobutanoate) and polymers and copolymers based on them, with the prospect of their further use as precursors of luminescent materials. 62 coordinating compounds of 3d- and 4f-metals were synthesized, 54 of them were obtained firstly. The structure and spectral-luminescent properties of all synthesized compounds are investigated. The analysis of the spectral luminescence properties of all synthesized compounds showed, that the relative intensity and efficiency of the luminescence of metal-polymers is several times higher, than that of monomeric complexes, the replacement of water molecules by the Phen molecule contributes to a significant increase Ilum., in heterometal complexes, depending on the electronic structure of 3d-metal both extinction (Cu, Ni) and sensitization (Zn) luminescence are observed.
