分别以双羟基、全羟基官能化的柱[5]芳烃大环为聚合单体, 1,4-二(4-醛基苯基)苯为交联剂, 通过酚醛缩合反应一步聚合得到了两种新型的酚醛多孔有机聚合物(PRP-1PRP-2). 通过固体核磁碳谱(13C CP/MAS NMR)、傅里叶变换红外光谱(FT-IR)、X射线粉末衍射(PXRD)、扫描电子显微镜(SEM)、氮气和二氧化碳吸脱附和热重分析(TG)对聚合物材料进行了表征. 结果表明柱[5]芳烃大环上的羟基数量对聚合物结构具有显著影响, 具有更多羟基数量的PRP-2的比表面积是PRP-1的10倍以上. 两个聚合物均可用于非均相催化二氧化碳(CO2)和环氧化物的环加成反应, 而且PRP-2展现出更高的转化率.

Two new phenolic resin porous organic polymers PRP-1, PRP-2 were obtained by one-step polymerization of phenolic resin reaction using functionalized pillar[n]arene and 1,4-bis(4-formylphenyl)benzene as polymerization monomers. The pore characters of PRP-1 and PRP-2 were evaluated by solid-state nuclear magnetic carbon spectroscopy (13C CP/MAS NMR), fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (PXRD), scanning electron microscopy (SEM), nitrogen and carbon dioxide adsorption and desorption, and thermogravimetric analysis (TG). The results showed that mutilid-hydroxyl groups on the aromatic macrocycles of pillar[5]arene significantly affect the polymer structure, and the specific surface area of PRP-2 with a higher number of hydroxyl groups is more than 10 times higher than that of PRP-1. Polymers PRP-1 and PRP-2 can be used for non-homogeneous catalytic carbon dioxide (CO2) conversion, and PRP-2 exhibits higher conversion. This work shows that the functionalized pillar[n]arene has a potential application in organic porous polymers.
