Abstract

A metallosupramolecular [Pd₂L₄]⁴⁺ cage can be cleanly converted into a [Pd₂L₂Cl₄] metallo-macrocycle upon addition of chloride ions. The process is reversible, treatment of the [Pd₂L₂Cl₄] macrocycle with silver(i) ions regenerates the [Pd₂L₄]⁴⁺ cage. Additionally, it is shown that guest molecules could be released on chloride triggered cage dis-assembly and taken up anew on re-assembly.
