Fig. 1. Equilibrium concentrations of MOF linker species determined from the coupled equilibria of the seesaw model. Linker–metal ([LM]) and protonated linker ([LH]) concentrations calculated as a function of initial metal ion ([M⁺]) and proton ([H⁺]) concentrations. Inset: [LM] calculated as a function of initial [M⁺] for a range of [H⁺]. Initial concentrations were chosen from typical experimental conditions reported here.
