We have fabricated a pillar[5]arene-based conjugated polymer, pillar[4]arene[1]terephthalic acid-derivatized poly-p-phenylene pillar[4]arene[1]terephthamide (P[5]-PPTA), which demonstrated exceptional adsorption capability toward low-molecular-weight alkylamines, alcohols, and carboxylic acids in water. In addition, P[5]-PPTA could be thermally reactivated and reused at least five times without obvious decrease of adsorption capability. A mechanistic study indicated that the absorption results from the host–guest interaction between the pillar[5]arene rings in P[5]-PPTA and the low-molecular-weight short-chain alkyl derivatives.

一种从水中去除低分子量有机酸，胺和醇的[5]芳烃共轭聚合物

我们制备了一种基于支柱[5]芳烃的共轭聚合物，支柱[4]芳烃[1]对苯二甲酸衍生的聚对苯撑支柱[4]芳烃[1]对苯二甲酸酰胺（P [5] -PPTA），对水中的低分子量烷基胺，醇和羧酸具有出色的吸附能力。此外，P [5] -PPTA可以热活化并重复使用至少五次，而吸附能力不会明显降低。一项机理研究表明，吸收是由于P [5] -PPTA中的支柱[5]芳烃环与低分子量短链烷基衍生物之间的主客体相互作用而产生的。
