Controlling Gas Selectivity in Molecular Porous Liquids by Tuning the Cage Window Size
2019-11-12T23:33:06Z (GMT) by
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.
