Water-soluble copolymers of p-methacrylamidobenzoic acid (MABA) with neutral comonomers (N-vinylpyrrolidone (VP), N-methyl-N-vinylacetamide (MVAA), N-methacryloyl glucosamine (MAG)) and anionic comononer sodium styrene sulfonate (NaSS) were synthesized by radical copolymerization. The interactions between the prepared copolymers and Tb³⁺ ions in aqueous solutions were studied; the significant influence of chemical structure of a comonomer on luminescence intensity of Tb³⁺ complexes with the copolymers was revealed. The luminescence intensity of Tb³⁺ complexes with the copolymers containing N-vinylamide units (VP, MVAA) is three times more intense than that observed for the complexes between Tb³⁺ and MAG-containing copolymers. In the case of NaSS-containing copolymers, the luminescence intensity is controlled by the values of binding constants between Tb³⁺ and MABA and the content of MABA units in a copolymer. The studied copolymers and their complexes with Tb³⁺ have low cytotoxicity and a pronounced antiviral activity against human respiratory syncytial virus.

对甲基丙烯酰氨基苯甲酸 (MABA) 与中性共聚单体（N-乙烯基吡咯烷酮 (VP)、N-甲基-N-乙烯基乙酰胺 (MVAA)、N-甲基丙烯酰氨基苯甲酸 (MAG)）和阴离子共聚单体苯乙烯磺酸钠 (NaSS) 的水溶性共聚物）通过自由基共聚合成。研究了所制备的共聚物与水溶液中Tb ³⁺离子的相互作用；揭示了共聚单体的化学结构对Tb ³⁺与共聚物的配合物的发光强度的显着影响。 Tb ³⁺与含有N-乙烯基酰胺单元(VP、MVAA)的共聚物的配合物的发光强度是Tb ³⁺与含有MAG的共聚物之间的配合物的发光强度的三倍。在含NaSS的共聚物的情况下，发光强度由Tb ³⁺和MABA之间的结合常数值以及共聚物中MABA单元的含量控制。所研究的共聚物及其与Tb ³⁺的复合物具有低细胞毒性和对人呼吸道合胞病毒的显着抗病毒活性。
