To overcome the challenges of global warming and environmental pollution it is mandatory to reduce the concentration of atmospheric carbon dioxide (CO2), which is largely accumulated in air through the combustion of fossil fuels. Thus, sequestration of CO2 through physisorption on solid adsorbents and their successful conversion into value added fine chemicals are the major priority areas of research today. Innovation of efficient solid CO2‐philic adsorbents together with their high mechanical/chemical stability and regeneration efficiency are the most challenging objectives to achieve this goal. In this context, porous organic polymers (POPs) owing to their high specific surface area, chemical stability, nanoscale porosity and structural diversity have huge potential to play as selective CO2 adsorbent. POPs synthesized through large varieties of reactive monomers via simple and convenient chemical routes can be the ideal adsorbents for the CO2 storage and fixation reactions. A wide range of POPs can be synthesized from different multidentate amines, aldehydes, carboxylic acids or triazine monomers through the polycondensation reactions or solid state condensation reactions. Ease of synthesis, uniform pore width together with high surface area and surface basic sites (nitrogen and other heteroelements) play crucial role in the CO2 absorption and conversion reactions. This review provides a concise account in designing POPs and their application in CO2 adsorption and fixation into reactive organic molecules for the synthesis of fuels and value added fine chemicals.

用于CO2储存和转化反应的多孔有机聚合物
为了克服全球变暖和环境污染的挑战，必须降低大气中二氧化碳（CO 2）的浓度，该浓度主要通过化石燃料的燃烧而累积在空气中。因此，通过对固体吸附剂的物理吸附来隔离CO 2并将其成功转化为增值精细化学品是当今研究的主要优先领域。创新高效固体CO 2亲电子吸附剂及其高的机械/化学稳定性和再生效率是实现该目标的最具挑战性的目标。在这种情况下，由于多孔有机聚合物（POPs）的高比表面积，化学稳定性，纳米级孔隙率和结构多样性，它们具有作为选择性CO 2吸附剂的巨大潜力。通过简单，便捷的化学路线，通过多种反应性单体合成的POPs可能是CO 2的理想吸附剂储存和固定反应。可以通过缩聚反应或固态缩合反应由不同的多齿胺，醛，羧酸或三嗪单体合成多种POP。易于合成，均匀的孔径以及高表面积和表面碱性位点（氮和其他杂元素）在CO 2吸收和转化反应中起着至关重要的作用。这篇综述为设计持久性有机污染物及其在CO 2吸附和固定到反应性有机分子中以合成燃料和增值精细化学品方面的应用提供了简要说明。
