A series of metalized C‐PIM‐M (M = Na⁺, Mg²⁺, Al³⁺, PIMs = polymers of intrinsic microporosity) materials were prepared from a carboxyl‐functionalized PIM (C‐PIMs). The C‐PIM‐Na exhibited a high CO₂ adsorption capacity of 2.44 mmol/g and extreme low CH₄ uptake of 0.28 mmol/g at 273 K and 101 kPa among three metallated PIMs. It showed remarkably high CO₂/CH₄ and CO₂/N₂ selectivities at both 273 and 293 K due to an advantageous pore‐blocking effect of Na⁺ cation.

通过合成后金属化有效提高固有微孔性聚合物对CH2和N2的CO2选择性和吸附能力

用羧基官能化的PIM（C-PIM）制备了一系列金属化的C-PIM-M（M = Na ⁺，Mg 2 ⁺，Al ³⁺，PIMs =具有固有微孔性的聚合物）材料。在三个金属化PIM中，C-PIM-Na在273 K和101 kPa处显示出2.44 mmol / g的高CO ₂吸附容量和0.28 mmol / g的极低CH ₄吸收量。由于Na ⁺阳离子具有有利的孔阻作用，它在273和293 K处显示出很高的CO ₂ / CH ₄和CO ₂ / N ₂选择性。
