The stability of MOFs…︁ …︁ (metal–organic frameworks) has been compared to understand relative chemical and thermal stabilities of isotypic porous MOFs (metal–benzenedicarboxylates; M-BDCs). The chemical stability of MOFs depends on the inertness of central metal ions. On the other hand, the bond strength of common metal oxides determines the thermal stability of MOFs. For more details, see the Full Paper by S. H. Jhung et al. on page 6437 ff.
