The rapid accumulation of CO₂, as the main component of greenhouse gas, causes the global warming and significant climatic variation along with a series of environmental problems. At the moment, the adsorption and capture of CO₂ is identified as one of the most promising and effective methods to control and reduce CO₂. Hence, it is in urgent need of constructing highly efficient porous materials with excellent stability to capture CO₂. A porous organic polymer (denoted as sf-PTPTCz) is firstly designed and synthesized by the FeCl₃-trigged oxidative coupling polymerization of tetrakis (4-(9H-carbazol-9-yl)phenyl)methane (TPTCz) via the solvent-free mechanochemical approach, which is an environmentally friendly preparation method and industrialized mass preparation. The as-synthesized porous material is further investigated by ¹³C solid-state NMR, Fourier transform infrared, powder X-ray diffraction, transmission electron microscope, scanning electron microscope, and gas sorption. By virtue of high surface area and excellent stability, the as-synthesized porous sample exhibits a high CO₂ adsorption ability and an excellent selectivity of CO₂ over N₂.

作为温室气体的主要成分，CO ₂的快速积累引起了全球变暖和重大的气候变化以及一系列环境问题。目前，CO ₂的吸附和捕获被认为是控制和减少CO ₂的最有希望和最有效的方法之一。因此，迫切需要构建具有优异的稳定性以捕获CO _2的高效多孔材料。首先通过FeCl ₃引发的四（4-（9H-咔唑-9-基）苯基）甲烷（TPTCz）的FeCl ₃引发的氧化偶联聚合，设计并合成了一种多孔有机聚合物（称为sf- PTPTCz）。无溶剂机械化学方法，这是一种环境友好的制备方法，已工业化批量制备。通过¹³ C固态NMR，傅立叶变换红外光谱，粉末X射线衍射，透射电子显微镜，扫描电子显微镜和气体吸附进一步研究了合成后的多孔材料。通过高表面积和优异的稳定性，所合成的多孔样品表现出高的CO ₂吸附能力和优异的CO ₂对N _2的选择性。
