Abstract
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 radi-cal copolymerization.The interactions between the prepared copolymers and Tb3+ions in aqueous solutions were studied;the significant influ-ence 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.
