Pressure-induced postsynthetic cluster anion substitution in a MIL-53 topology scandium metal-organic framework.

ABSTRACT: Postsynthetic modification of metal-organic frameworks (MOFs) has proven to be a hugely powerful tool to tune physical properties and introduce functionality, by exploiting reactive sites on both the MOF linkers and their inorganic secondary building units (SBUs), and so has facilitated a wide range of applications. Studies into the reactivity of MOF SBUs have focussed solely on removal of neutral coordinating solvents, or direct exchange of linkers such as carboxylates, despite the prevalence of ancillary charge-balancing oxide and hydroxide ligands found in many SBUs. Herein, we show that the μ₂-OH ligands in the MIL-53 topology Sc MOF, GUF-1, are labile, and can be substituted for μ₂-OCH₃ units through reaction with pore-bound methanol molecules in a ver
