A macrocyclic aromatic pyridine pentamer was found to exhibit patterned recognition of metal ions and efficiently extract larger ions, such as Cs(+), Ba(2+), Tl(+), Au(+), K(+) and Rb(+) preferentially over the other 18 smaller metal ions from the aqueous phase into the chloroform layer.
人们发现一种大环芳香吡啶五聚体对金属离子具有选择性识别能力，并且能有效地从水相中优先萃取较大的离子，如Cs(+)、Ba(2+)、Tl(+)、Au(+)、K(+)和Rb(+)，而不是其他18种较小的金属离子，使其进入氯仿层。
