Water-Soluble Polymer Ligands for Binding of Terbium Ions

Water-soluble terpolymers of 2-deoxy-N-methacryloylamidoglucose, methacryloylacetone, and methacrylic acid have been synthesized by the of radical copolymerization method. It has been shown that they form luminescent complexes with terbium ions in aqueous solutions. The luminescence intensity depends on the ratio of the components and remains constant in the presence of CaCl2 and NaCl. These terbium-binding terpolymers can be the basis for the creation of both luminescent probes and radioactive pharmaceuticals where a short-lived γ-emitter 161Tb is used for cancer ratiotherapy.
