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.
