The exchange of lanthanide(III) ions (Ln3+) between a solution and a coordination polymer (CP) formed by cerium(III) or samarium(III) ion and an organophosphorous ligand has been studied. The CPs exhibit distinctive Ln3+ affinity that varies with a small change in its framework, depending on the central Ln3+.
