控制孔窗尺寸是调节多孔固体中气体选择性的标准方法。在这里,我们提出第一个例子,将其转化为由有机笼分子形成的分子多孔液体。通过化学合成减小笼窗尺寸将选择性从 Xe 选择性切换为 CH4 选择性,这可以使用 129Xe、1H 和脉冲场梯度 NMR 光谱来理解。
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 using129Xe,1H, and pulsed‐field gradient NMR spectroscopy.
