PG - 1322-1331 LID - 10.1039/c8sc04138e [doi] AB - Stoichiometric reduction reactions of two metal-organic frameworks (MOFs) by the solution reagents (M = Cr, Co) are described. The two MOFs contain clusters with Ti(8)O(8) rings: Ti(8)O(8)(OH)(4)(bdc)(6); bdc = terephthalate (MIL-125) and Ti(8)O(8)(OH)(4)(bdc-NH(2))(6); bdc-NH(2) = 2-aminoterephthalate (NH(2)-MIL-125). The stoichiometry of the redox reactions was probed using solution NMR methods. The extent of reduction is greatly enhanced by the presence of Na(+), which is incorporated into the bulk of the material. The roughly 1 : 1 stoichiometry of electrons and cations indicates that the storage of e(-) in the MOF is tightly coupled to a cation within the architecture, for charge balance.
