Abstrakt: Control of pore window size is the standard approach for tuning gas selectivity in porous solids. Here, we present the first example where this is translated into a molecular porous liquid formed from organic cage molecules. Reduction of the cage window size by chemical synthesis switches the selectivity from Xe-selective to CH 4 -selective, which is understood using 129 Xe, 1 H, and pulsed-field gradient NMR spectroscopy.
