The structural organization and luminescent properties of macromolecular metal complexes containing terbium ions

Copolymers of N-alkylmethacrylamides with various isomers of N-methacryloyl aminobenzoic acids were synthesized and used to obtain the macromolecular m etal complexes (MMCs) with Tb3+ ions in aqueous solutions. The luminescence spectra of Tb3+ ions in these MMCs were measured, the composition and stru ctural features of complexes were determined, and stability of these system s was assessed. For this purpose, stability of the Tb3+-copolymer contacts was studied in the systems involving polymer-competitors (polyacrylic and p olymethacrylic acids). The effect of Tb3+ ions on the structural organizati on of macromolecules was characterized by the relaxation times determined u sing the method of polarized luminescence.
