The synthesis and successful activation of IRMOF-8 (Zn4O(ndc)3, ndc = naphthalene-2,6-dicarboxylate) is presented. Room temperature synthesis effectively suppresses interpenetration. Although conventional activation under reduced pressure leads to structural collapse, activation by flowing supercritical CO2 yields a guest-free material with a BET surface area of 4461 m2 g−1.
