To understand the origin of the effect of scrambling on the gas sorption properties of both families of cages, we undertook Dubinin-Radushkevich analysis as an approximation to evaluate the relative contributions from micro-and mesoporosity in the cages. This analysis can be used to calculate the micropore volume within a sample, which is derived from the intercept of the Dubinin-Radushkevich plot with the y-axis, log(V), where V is the adsorbed volume of N2 (plots are provided alongside the corresponding N2 isotherm in the supporting information). This was then compared with the total pore volumes the solids, which were obtained from the adsorbed volume of N2 observed at higher values of P/P0. Fig. presents this analysis for the family of cages [Cu4(L)4-x(CH3L)x]. The scrambled cages display higher total pore volumes than the respective homoleptic materials. At the same time, the relative contribution to this volume from microporosity decreases: for the scrambled material [Cu4(L)2(CH3L)2] this is approximately 55%, compared to 78% for the cage [Cu4(CH3L)4]. Therefore, we suggest that the most important effect of the scrambling process is the creation of mesopores, arising from inefficient packing of the cages.
