Two hyper-cross-linked polymers (HCPs) were readily prepared through one-pot Friedel-Crafts reaction using methylene and carbonyl as the rigid cross-linking bridges. Unexpectedly, the methylene cross-linked PDV-pc-1 (686 m²/g and 0.37 cm³/g, respectively) owned a little higher Brunauer-Emmett-Teller surface area and pore volume than the carbonyl cross-linked PDV-pc-2 (635 m²/g and 0.33 cm³/g, respectively), while PDV-pc-2 had a higher CO₂ uptake (86 mg/g) than PDV-pc-1 (64 mg/g), the introduced carbonyl groups and the better microporosity were the main reasons. Specially, the CO₂ uptake had a good linear correlation with the ultramicropores (d < 1.0 nm) (R² = 0.998). In particular, the CO₂ uptake of the direct carbonized PDVC-2 (57 mg/g) was almost identical to the KOH-activated carbonized PDVC-KOH (62 mg/g) at 0.15 bar in spite of its much lower Brunauer-Emmett-Teller surface area, proving that PDVC-2 had a good prospect of CO₂ capture from harsh flue gas conditions.

通过使用亚甲基和羰基作为刚性交联桥的一锅法式Friedel-Crafts反应，可以轻松制备两种超交联聚合物（HCP）。出乎意料的是，亚甲基交联的PDV-pc-1（分别为686 m ² / g和0.37 cm ³ / g）具有比羰基交联的PDV-pc更高的Brunauer-Emmett-Teller表面积和孔体积-2（分别为635 m ² / g和0.33 cm ³ / g），而PDV-pc-2的CO ₂吸收量（86 mg / g）比PDV-pc-1（64 mg / g）高。引入的羰基和更好的微孔性是主要原因。特别地，CO _2的吸收与超微孔（d <1.0 nm）具有良好的线性相关性（R ² = 0.998）。尤其是，直接碳化的PDVC-2（57 mg / g）的CO ₂吸收量与0.15 bar的KOH活化的碳化PDVC-KOH（62 mg / g）几乎相同，尽管其Brunauer-Emmett较低。 -塔勒表面积，证明PDVC-2具有从恶劣烟气条件下捕获CO ₂的良好前景。
