Silver ion-induced chiral enhancement by argentivorous molecules

Abstract

Optically active tetra-armed cyclens with an asymmetric chiral centre in the cyclen moiety were synthesized and were shown to enhance chirality and control of enantiomers on complexation with Ag⁺. Binding studies of the Ag⁺ complex demonstrated that Ag⁺ preferentially interacts with electron-rich substituents over other aromatic substituents.
