A new 24-membered tetralactam with two ethylene dioxy moieties and a mirror symmetry is prepared. Its binding abilities for Na+, Ca2+, Mg2+ and Zn2+ ions was determined by an extraction procedure. A good affinity and a high selectivity are observed for Ca2+. The stability constant of the tetralactam:Ca2+ 1:1 complex is estimated by UV spectrophotometry in THF solution.
制备具有两个亚乙二氧基部分和镜像对称的新的24元四内酰胺。通过萃取程序测定其对Na +,Ca 2 +,Mg 2+和Zn 2+离子的结合能力。对Ca 2+观察到良好的亲和力和高选择性。通过在THF溶液中的UV分光光度法估计四内酰胺:Ca 2+ 1:1配合物的稳定性常数。
