Abstract

Abstract : Post‐metalation modification based on ligand exchange on the metal centers is a useful strategy to control the guest recognition behavior of a metal‐containing macrocyclic host. The two axial piperidine ligands at diagonal positions in the cobalt(III) dinuclear macrocyclic host, [LCo2 (pip)4 ] 2+ (pip=piperidine), were site‐selectively replaced with pyridine or acetato ligands. The replacement with acetato ligands significantly enhanced the Na + recognition ability. More information can be found in the Full Paper by S. Akine et al. on page 7595 .
