group of aromatic and tetrahydrofuran rings, number of ether oxygens, and terminal hydroxyl group of the ionophores on the ion transport ability and selectivity were investigated. The hydrophobic groups increased total amount of transported ions as well as partition coefficients. The ionophore, 5, which contains five ether oxygens, two aromatic rings, and o-toluic acid moiety transported K+ selectively
ω-羟基羧酸(3, 5, 6, 7, 10, 12, 14, 17, 18, 20, and 22)带有 2-6 个醚氧和芳香环,带或不带四氢呋喃环,ω-甲氧基和合成了 5 (8 和 9) 的 ω-苄氧基衍生物。它们被用作碱金属离子通过液膜的主动和竞争性传输以及将碱金属离子提取到有机层的载体。研究了芳香环和四氢呋喃环的疏水基团、醚氧的数量和离子载体的末端羟基对离子传输能力和选择性的影响。疏水基团增加了传输离子的总量以及分配系数。离子载体,5,包含五个醚氧,两个芳环,和邻甲苯甲酸部分通过 1,2-二氯乙烷选择性地通过 Na+ 和 Li+ 传输 K+,与提取实验一致。间位和对位取代的异构体 6 和 7 没有表现出通过 1...
