Acid–Base-Driven Interconversion between a Mononuclear Complex and Supramolecular Coordination Polymers in a Terpyridine-Functionalized Dioxocyclam Ligand
A polytopic cyclam−bis-terpyridine ligand has been used to accomplish an acid–base-triggered formation of either a mononuclear neutral complex or metallopolymers with Cu2+ ions. A controlled interconversion between these two forms was achieved through the reversible displacement of a Cu2+ cation from the macrocycle to the terpyridine units.
