Increased Electrical Conductivity in a Mesoporous Metal–Organic Framework Featuring Metallacarboranes Guests

Nickel­(IV) bis­(dicarbollide) is incorporated
in a zirconium-based
metal–organic framework (MOF), NU-1000, to create an electrically
conductive MOF with mesoporosity. All the nickel bis­(dicarbollide)
units are located as guest molecules in the microporous channels of
NU-1000, which permits the further incorporation of other active species
in the remaining mesopores. For demonstration, manganese oxide is
installed on the nodes of the electrically conductive MOF. The electrochemically
addressable fraction and specific capacitance of the manganese oxide
in the conductive framework are more than 10 times higher than those
of the manganese oxide in the parent MOF.
