16-Crown-5 derivatives with double oxyethylene side-arms of various chain lengths were synthesized and their cation-binding abilities were assessed. In addition to the general enhancement in extractabilities for most cations, peak extractabilities were observed for the size-fitted cations, i.e. Na+ and Ag+, at a specific length of the side-arm.
我们合成了具有不同链长的双氧
乙烯侧臂的 16-Crown-5 衍
生物,并评估了它们的阳离子结合能力。除了对大多数阳离子的萃取能力普遍增强外,还观察到在侧臂的特定长度上,尺寸拟合阳离子(即 Na+ 和 Ag+)的萃取能力达到峰值。
