利用铜离子介导的Ullmann反应，通过自下而上的策略合成了一种结构明确的硝基功能化多孔芳香骨架（NO2-PAF-1）。该合成路线具有成本效益，并且对于大规模制备是稳健的。所获得的NO2-PAF-1的Brunauer-Emmett-Teller（BET）比表面积高达610 cm 2 g-1，具有微/中孔性。由于硝基与CO2分子之间的强相互作用，其CO2吸收量高于PAF-1，这通过CO2吸附的增强的等排热（38.4 kJ mol−1）来证明。
A well-defined nitro group functionalized porous aromatic framework (NO2-PAF-1) was synthesized via a bottom-up strategy using a copper-mediated Ullmann reaction. The synthetic route is cost-efficient and robust for large scale preparation. The Brunauer–Emmett–Teller (BET) specific surface area of the obtained NO2-PAF-1 is up to 610 cm2 g−1 with micro/mesoporosity. Its CO2 uptake was measured to be higher than that of PAF-1 due to the strong interaction between the nitro groups and CO2 molecules, proven by the enhanced isosteric heat of CO2 adsorption (38.4 kJ mol−1).
