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 -selective, which is understood using Xe, H, and pulsed-field gradient NMR spectroscopy.
控制孔窗大小是调节多孔固体中气体选择性的标准方法。在此，我们展示了首个将此方法转化为由有机笼状分子形成的分子多孔液体的例子。通过化学合成减小笼窗大小可将选择性从对氙的选择性转变为对甲烷的选择性，这可通过氙、氢和脉冲场梯度核磁共振光谱来理解。
