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 CH4‐selective, which is understood using 129Xe, 1H, and pulsed‐field gradient NMR spectroscopy.

Exceptional solvation properties of diiodomethane and its inertness towards organometallics make this solvent a good candidate for NMR solvent-of-choice, in particular, for the acquisition of insensitive spins. Better solvation properties of diiodomethane were associated with formation of the uniquely strong solvent-(metal complex) halogen bonding.
