摘要
We have fabricated a pillar[S]arene-based con- jugated 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.
