title: Size-dependent patterned recognition and extraction of metal ions by a macrocyclic aromatic pyridone pentamer.
abstract: 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.
