supramolecular networks. These networks form 2-D hexagonal columnar lattices with thermal stability in some cases of up to 110°C. The design of such functional supramolecular systems was inspired by the bilayer fluid mosaic structure of the cell membrane. The lipid bilayer of the cell membrane, which in its ordered state acts as a barrier to the passage of polar molecules, was replaced with the semifluorinated
描述了基于第一代半氟化烷基取代的单树枝状分子(即minidendron)的两种AB 3锥形,自组装甲基丙烯酸酯单体(12和13)的合成和聚合。这些单体包含通过4'-羟甲基-1,4,7,10,13-五氧杂苯并环戊十五烷的酯化反应引入的苯并15冠5衍生物或通过四亚乙基的单酯化反应引入的荚果基团。二醇在其焦点处,并且两者在其外围均带有可聚合基团。相应的聚合物(14 – 16)自组装,然后自组织为超分子网络,通过疏水效应形成2D六方柱状晶格。这些网络由连续相组成,该连续相基于半氟化石蜡阻挡层,并分别由分别由苯并冠醚和四甘醇构成的离子选择性或离子活性通道以六边形阵列方式穿孔。用半氟化原子取代锥形单树枝状分子外围的烷基,引起自组装,然后自组织成超分子网络。这些网络形成二维六边形柱状晶格,在某些情况下,其在高达110°C的温度下具有热稳定性。此类功能性超分子系统的设计受到细胞膜的双层流体镶嵌结构的启发。
