Finally, we note that these measurements have also been applied to the larger-pore Zn2(dobpdc) framework. Qualitatively similar spectra were obtained, though the increase in pore size from 15 to 22 Å led to an increase in D// by a factor of 4 to 6 across a range of CO2 dosing pressures. These measurements therefore highlighted a straightforward means to tune transport properties through modification of the framework structure. Measurements and analysis for the Zn2(dobpdc) sample interestingly also supported non-zero diffusion between the MOF pores, which was tentatively attributed to defects in the MOF structure enabling additional transport pathways.
