摘要

以柱[5]芳烃为聚合单体(pillar[5]arene)

二甲醇缩甲醛(formaldehyde dimethyl acetal

FDA)为交联剂

通过Friedel-Crafts烷基化反应一步聚合得到一种新型的超交联多孔有机聚合物FDA-PP5

进一步通过脱甲基反应对其后修饰得到多羟基官能团化的多孔聚合物FDA-PP5-OH。结果表明

随着羟基的引入

FDAPP5-OH 的表面润湿性和比表面积均得到有效提升。吸附实验结果表明两种聚合物对亚甲蓝、中性红、甲基橙和四环素的吸附过程均符合Langmuir吸附模型

羟基官能团化的FDA-PP5-OH 具有更大的饱和吸附量和更快的吸附速率。

Abstract

A new type of hyper-crosslinked porous organic polymer FDA-PP5 was synthesized by one-step polymerization of Friedel-Crafts alkylation using pillar[5]arene as polymerization monomer and formaldehyde dimethyl acetal (FDA) as cross-linking agent. The polyhydroxyl functional porous polymer FDA-PP5-OH was further modified by demethylation. The results showed that the surface wettability and specific surface area of FDA-PP5-OH increased with the introduction of hydroxyl groups. The adsorption experimental results show that the adsorption processes of the two polymers for methylene blue

neutral red

methyl orange and tetracycline are in accordance with the Langmuir adsorption model

and the hydroxyl functionalized FDA-PP5-OH has larger saturated adsorption capacity and faster adsorption rate.
