Abstract

The effect of nanoscale confinement of a salt on its ionic conductivity was studied for [NEt₄][TFSI] melt-loaded in three isoreticular zirconium-based MOFs: UiO-66, UiO-67, and PCN-56. Conductivity of the MOF-salt composites was up to a factor of 50 higher than the pure salt, and maximized with slightly less than full loading of the MOFs.
