Abstract
A selective digest of linear anion receptors based on different aromatic skeletons
is presented. Since the structures of anions vary from one to another, different strategies
have been developed over recent years in order to bind anions efficiently and selectively.
Rigidity, number of hydrogen bond donors, steric hindrance, and special preorganization
of linear receptors are analyzed to shed light on the rational design of anion receptors.
