已经证实，初级化学结构和拓扑结构的微小差异会影响巨型表面活性剂的自组装行为，然而，区域构型效应的报道很少。在这里，我们系统地研究了一系列双链表面活性剂区域异构体的自组装行为，这些异构体包括一个亲水性多面体低聚倍半硅氧烷(POSS)头部和两个相同的疏水聚苯乙烯(PS)尾部，它们分别以对位、间位和邻位构型连接。结合小角X射线散射和透射电子显微镜的表征，研究了每个样品的相行为，并绘制了三种异构体与PS尾部相对分子质量的相图。结果表明，区域构型对巨型表面活性物质异构体的自组装行为有显著影响，包括有序到无序(ODT)和有序到或...
It has been established that a minute difference of the primary chemical and topological structures influences the self-assembly behaviors of giant surfactants; however, the regio-configuration effect has been rarely reported. Herein, we report a systematic study on the self-assembly behaviors of a series of double-chain giant surfactant regio-isomers, which consist of a hydrophilic polyhedral oligomeric silsesquioxane (POSS) head and two identical hydrophobic polystyrene (PS) tails with various molecular weights tethered in para-, meta-, and ortho-configurations, respectively. Small-angle X-ray scattering and transmission electron microscopy characterizations have been combined to investigate the phase behaviors of each sample and construct the phase diagrams for the three isomers with respect to the molecular weights of PS tails. It is observed that the regio-configuration significantly impacts the self-assembly behaviors of the giant surfactant isomers, including order-to-disorder (ODT) and order-to-or...
