A novel kind of functional organic microporous polymer is designed by introducing polar organic groups (P=O and P=S) and electron-rich heterocyclic into the framework to obtain high carbon dioxide capture capacity. The estimated Brunauer-Emmett-Teller (BET) surface areas of these polymers are about 600 m(2) g(-1) and the highest CO2 uptake is 2.26 mmol g(-1) (1.0 bar/273 K). Interestingly, the polymer containing P=O groups shows greater CO2 capture capacity than that containing P=S groups at the same temperature. In addition, these polymers show high isosteric heats of CO2 adsorption (28.6 kJ mol(-1) ), which can be competitive with some nitrogen-rich networks. Therefore, these microporous polymers are promising candidates for carbon dioxide capture.
设计了一种新型的功能有机微孔聚合物，通过在骨架中引入极性有机基团（P=O 和 P=S）和富电子杂环来获得高二氧化碳捕获能力。这些聚合物的估计 Brunauer-Emmett-Teller（BET）表面积约为 600 m(2) g(-1)，最高 CO2 吸收量为 2.26 mmol g(-1)（1.0 bar/273 K）。有趣的是，在相同温度下，含有 P=O 基团的聚合物比含有 P=S 基团的聚合物具有更大的二氧化碳捕获能力。此外，这些聚合物表现出高的 CO2 吸附等焓（28.6 kJ mol(-1)），可与一些富氮网络相竞争。因此，这些微孔聚合物是二氧化碳捕获的有前途的候选物。
