| Abstract: | The influence of the composition and structure of a macromolecular ligand on the efficiency of energy transfer in complexes of EuIII and TbIII with ligands based on acrylic acid has been studied. It has been found that a decrease in the size of an alkyl group of methacrylic esters and a low content of acrylic moieties of EuIII complexes with copolymers increase the efficiency of EuIII concentration quenching. Insertion of noncoordinative alkyl methacrylate into the polymeric chain results in an increase in the efficiency of energy transfer from Tb3+ to Eu3+.Translated fromIzvestiya Akademii Nauk.
