Three novel polymerizable amphiphiles with a sorbyl-substituted head group were synthesized and systematically characterized. These amphiphiles are neutral in charge. None of these molecules forms vesicles by itself, presumably due to lack of amphiphilicity and/or extensive head group interaction. Therefore, mixed vesicles were formed with other fluid lipids such as DPenPC, eggPC, or DOPC. We investigated
合成并系统地表征了三种具有山梨酰基取代的头部基团的新型可聚合两亲物。这些两亲物是中性的。这些分子中没有一个单独形成囊泡,可能是由于缺乏两亲性和/或广泛的头基相互作用。因此,混合囊泡与其他流体脂质如 DPenPC、eggPC 或 DOPC 形成。我们研究了这些混合物在囊泡和朗缪尔薄膜中的性质。Langmuir 等温线显示所有三个分子都形成单层。然而,混合单层的等温线表明两种成分在很大程度上与混合脂质不混溶。在聚合条件下,这些两亲物的混合囊泡形成低聚物,这表明尽管头部基团较大,但它们形成中间相。
