To investigate the consequences of solvent choices on the successfulness of the activation process, the geometricalmechanical relationship was re-analyzed based on the last solvent used to activate the MOFs. The bulk modulus was plotted against the void fraction and PLD, while mapping the last solvents as a color bar based on their surface tension (Figure ), or boiling point (Figure ). In these plots, MOFs those were activated from a mixture of solvents were excluded. As well, we excluded the cases where it was difficult to identify the last solvent among the many tested solvents. Given that considerable portion of the MOFs were activated (or attempted) using the supercritical CO2 or freeze-drying methods, so the surface tension was set to zero, because in these cases there is no direct liquid-vapor transition. From Figure , it is very clear that the MOFs activated from a solvent with high surface tension (red color) have high bulk modulus and low void fraction, although fewer data points fall outside. Here, the solvent with highest surface tension is water, with a surface tension of 72.7 mN/m at 20 °C. In contrast, MOFs activated from a solvent with low/zero surface tension are located in the region with low mechanical strength and high porosity. The same arguments are true, when the geometrical-mechanical relationship mapped in term of the normal boiling of the last solvent (Figure ). Here, the solvent with the highest required temperature for evaporation is DMF with a normal boiling point of 153 °C.
