摘要: Abstract Two kinds of POSS-based microporous organic polymers (PMOPs) were prepared by cost-effective Friedel-Crafts reaction octaphenylsilsesquioxanes with p-dimethoxybenzene (PMOP-1) or cyanuric chloride (PMOP-2). PMOP-1 high surface area 806 m2 g−1 exhibited reasonable CO2 adsorption (2.59 mmol g−1, 273 K/1 bar) and selectivity, whereas PMOP-2 lower (559 m2 g−1) showed a higher CO2/N2 selectivity (30.0) CO2/CH4 (6.8) at 273 K/1 bar due to the amount nitrogen incorporated within structure. The correlation between performance PMOPs in capture/separation their properties such as area, active sites, heat was investigated. combination method, thermal stability, selective make these materials potential candidates for application capture separation technology.
