T-型表面两亲分子形成的复杂纳米液晶超分子结构

T-型表面两亲分子是近年成功设计的一类三嵌段液晶分子之一,这类分子具有与三嵌段波拉两亲分子相反的拓扑构型。通过调节分子中各不相容嵌段的相对体积大小,能获得多种新型的二维多角形蜂窝状纳米结构,实现从分子水平上控制其自组装行为,获取超分子纳米结构的目的,为设计具有二维纳米结构的新型功能材料提供了崭新的途径。综述了这类表面两亲分子的自组装行为及它们形成的多种新型复杂液晶超分子结构。

Complicated Nano Liquid Crystalline Supra-structure Formed by T-shaped Facil-amphiphiles

T - shaped facial - amphiphilies with lateral polar chains are one of the most successfully designed triblock liquid crystals which can form series of nano - scale liquid - crystalline （LC） arrays of polygonal honeycomb like cylinder networks, it opens a new way to design 2D-nano-scale arrays for potential nanotechnological applications. In this paper the molecular self-organization and the complicated 2D-supramolecular structures of these facial-amphiphiles are summarized.
