A monomer – 2-methyl-5-phenylpentene-1-dione-3,5, its solvent metal complex  Eu(III)-water, hybrid metal complex Eu(III)-phenanthroline, new metallopolymers based on them are obtained. The results of above studies have shown that the configuration of the chelate unit is unchanged during polymerization. Using the electron microscopy the homogeneity of metal distribution in the polymer matrix of synthesized metallopolymer was confirmed. The similarity of monomers electronic absorption spectra with polymers spectra confirms the identical coordinative environment of lantanide ions in both cases. The solubilization of europium β-diketonate complexes with phenanthroline was shown to change luminescence intensity in such complexes.
