Two cluster-based microporous MOFs containing coordination unsaturated metal(ii) sites (or open metal(ii) sites) have been constructed from boxlike or cagelike {M3}ₓ SBUs. They both exhibit highly selective uptake for CO₂ over CH₄ and N₂ under ambient conditions. More importantly, MOF-1 also provides an ideal luminescence sensor for selective probing Ba²⁺ and Cu²⁺ ions based on significant luminescence enhancement or quenching.
