It is difficult for the same molecule to form vesicular assemblies in water and alipatic hydrocarbon (oil), respectively. Here, we report that chiral oligo(methylene-p-phenyleneethynylene)s bearing hydrophobic or hydrophilic side chains can take extended conformations to self-assemble into vesicle-like particles in a hydrophobic or hydrophilic solvent system. The self-assembly processes are highly independent of molecular design and chemical environments. Based on the analyses of TEM, UV, CD and PXRD data, it is plausible to expect that the vesicular membranes could be stabilized together by π–π stacking interactions between foldamer backbones and collective van der Waals interactions between side chains.

手性低聚（亚甲基-对-亚苯基-亚乙炔基）自组装成囊状颗粒，与侧链和溶剂的疏水性/亲水性无关

同一分子很难分别在水和脂肪烃（油）中形成囊状组装体。在这里，我们报道带有疏水性或亲水性侧链的手性低聚（亚甲基-对-亚苯基乙炔基）可以采取扩展构象，以在疏水性或亲水性溶剂系统中自组装成囊状颗粒。自组装过程高度独立于分子设计和化学环境。根据对TEM，UV，CD和PXRD数据的分析，可以预期，通过折叠夹骨架之间的π-π堆积相互作用和侧链之间的范德华力相互作用，可以使囊泡膜稳定在一起。
