Abstract
Eu(III) acrylatodibenzoylmethanate was synthesized with the aim of obtainin g luminescent macromolecular Ln(III) complexes with chromophores. It was ho mo- and copolymerized with methyl methacrylate. The compounds formed were c haracterized by elemental analysis, luminescence, and IR spectroscopy. The luminescence intensity of the macromolecular Eu(III) complexes containing d ibenzoylmethanate ions was shown to exceed the intensity of the monomeric c omplex by several times. The increase in the luminescence intensity when go ing from the monomer to copolymers is explained by the weakening of the que nching effect of the low state of the metal-ligand charge transfer.
