摘　　要：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-1、PRP-2).通过固体核磁碳谱(^(13)C 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(CO_(2))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(^(13)C 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(CO_(2))conversion,and PRP-2 exhibits higher conversion.This work shows that the functionalized pillar[n]arene has a potential application in organic porous polymers.
