Salt nanoconfinement in zirconium-based metal organic frameworks leads to pore-size and loading-dependent ionic conductivity enhancement
The nanoscale confinement of [NEt4][TFSI] in three isostructural MOFs enhanced the conductivity of composites relative to neat [NEt4][TFSI] by up to a factor of 50. The conductivity increases with the increase in pore size and maximum conductivity was achieved with a salt loading slightly less than that required for complete filling of the MOF pores. Read More
