AbstractNanoporous materials like metal–organic frameworks (MOFs) attract considerable attention as porous host for electrolytes like ionic liquids (ILs). The conductivity and mobility of the ions in the pores are among the key properties and their experimental quantification is of paramount importance. Here, three different approaches for the quantification of the ion conductivity of IL@MOF via electrochemical impedance spectroscopy (EIS) are compared: the material in the form of IL-impregnated MOF powders pressed into pellets between two planar electrodes, MOF films grown on substrates with deposited electrodes loaded with IL by impregnation, and the IL-loaded MOF films where excess IL is removed. Contact-angle measurements and EIS data show that the excess IL on the outer MOF surface of the film or pellet results in apparent conductivities, larger than the intrinsic conductivity of the IL@MOF. Removing the excess IL enables the experimental quantification of the intrinsic IL@MOF conductivity. Graphical abstract The ionic conduction of ionic liquid (IL) confined in nanoporous metal–organic framework (MOF) is explored via impedance spectroscopy, where the material is either in the form of pellets pressed from powder or in the form of thin films grown on suitable substrates. The different methods show substantially different results, attributed to excess IL on the external surface, and a method for recording the intrinsic IL@MOF conductivity is presented.
