Abstract

Water-soluble copolymers of sodium styrene sulfonate and 4-methacrylamidosalicylic acid of 93.7 mol % composition have been synthesized, and their interaction with terbium and gadolinium ions has been investigated to fabricate luminescent probes promising for their visualization in biomedical research. It has been shown that, in aqueous solutions in the copolymer concentration range 0.15–1.7 mg mL^–1 and at the ratio [Tb³⁺]/[COO^–] = 1, water-soluble luminescent metal polymer complexes with a luminescence lifetime of 823 µs are formed. When Tb³⁺ ions are partially replaced in the complex by Gd³⁺ ions, bimetallic complexes with intense luminescence are formed.

铽离子在苯乙烯磺酸钠与4-甲基丙烯酰胺水杨酸共聚物水溶液中的发光研究

合成了93.7摩尔%的苯乙烯磺酸钠和4-甲基丙烯酰胺水杨酸的水溶性共聚物，并研究了它们与铽和钆离子的相互作用，制备了在生物医学研究中有前景的发光探针。结果表明，在共聚物浓度范围为0.15 ~ 1.7 mg mL-1的水溶液中，当[Tb3+]/[COO -] = 1时，可形成发光寿命为823µs的水溶性发光金属聚合物配合物。当配合物中的Tb3+离子部分被Gd3+离子取代时，形成具有强发光的双金属配合物。
