Hydrophobic naphthalene‐based porous organic polymers achieving <scp> CH <sub>4</sub> </scp> / <scp> N <sub>2</sub>
The efficient adsorption separation of CH 4 /N 2 from low‐concentration methane mixtures is a crucial prerequisite for its resource utilization. However, the separation performance of the common adsorbents would be severely weakened under humid conditions. Herein, a series of hydrophobic and porous organic poly...
