The self‐assembly of a new type of three‐dimensional (3D) supramolecular polymers from tetrahedral monomers in both organic and aqueous media is described. We have designed and synthesized two tetraphenylmethane derivatives T1 and T2, both of which bear four tetrathiafulvalene (TTF) units. When the TTF units were oxidized to the radical cation TTF.+, their pre‐organized tetrahedral arrangement remarkably
描述了由四面体单体在有机介质和水性介质中自组装的新型三维(3D)超分子聚合物。我们设计并合成了两个四苯基甲烷衍生物T1和T2,它们都带有四个四硫富瓦烯(TTF)单元。当TTF单元被氧化成自由基阳离子TTF 。+,它们的预组织四面体排列显着增强了它们的分子间二聚作用,从而导致了新的3D球形超分子聚合物的形成。超分子聚合物的结构是根据UV / Vis吸收,电子顺磁共振,循环伏安法和动态光散射(DLS)分析,以及通过将这些特性与Pb的自组装结构比较得出的单,双和三位对照化合物。DLS实验显示,该球形超分子聚合物具有68纳米的流体动力学直径T1(75μ中号的乙腈溶液)和105纳米的T2(75μ中号)溶于水/乙腈(1:1)中。SEM和AFM实验也支持了在不同溶剂中形成的超分子聚合物的3D球形结构。
