摘要
大环番衍生物单体5,11,17,23-四叔丁基-25,27-二酰氯基-26,28-二羟基杯[4]芳烃(DC)与哌嗪通过界面聚合,制备了聚(杯芳烃-哌嗪)酰胺(D).化合物D在乙酸乙酯溶液中形成平均直径为28和164 nm的双分布囊泡形聚集体. 2,2'-联吡啶(bpy)对化合物D的交联作用可将囊泡转变为实心无规则交联网.水将交联网转变为两相界面处存在的泡沫.这个变化过程表明,化合物D在不同的诱导条件下可调整聚集状态,多重诱因使其最终形成宏观泡沫状自组装构筑.化合物D是一个集合芳香大环-小杂环,疏水-亲水、氢键供体受体、刚性-柔性及富π空腔等多种结构及自组装于一体的高分子结构,其分子链在不同诱因下改变扭曲和取向导致超分子交联网络的形成.这种可逆宏观自组装现象为自组装机理的理解及刺激-响应材料的开发提供了一种有价值的试材.
Calixarene derivative,5,11,17,23-tetra-tert-butyl-25,27-di(chloroacetyloxy)-26,28-dihydroxycalix[4]arene(DC),was used as organic phase monomer to prepare poly(calixarene-piperazine)amide(D)through interfacial polymerization with piperazine aqueous solution.Compound D showed induced self-assembly actions under different factors.It could self-associate into double distribution vesicles of average diameter of 28 and 164 nm,respectively.2,2′-bipyridine(bpy)crosslinked D into supermolecular network.H 2O turned{network}into foams at the interface of water-ethyl acetate.Foams are large-scale structure constructed by D and bpy and H 2O droven by weak intermolecular interaction includingπ-πstaking,hydrophobic-hydrophobic{interaction}and interfacial effect.This work provide a new material for large scale supermolecular building and stimuli-responsive function.
