含有亲水性聚环氧乙烷(PEO)链和多个亚苯基作为刚棒的刚棒-线团(rod-coil)分子,由于具有很强的π-π堆积作用和微相分离作用,可以在本体和溶液中产生有序排列形成各种组装体。材料的性能主要依靠分子聚集体来体现,因此研究分子聚集体的性质和用途成为当前超分子领域研究的重要内容。刚棒嵌段的形状影响着分子排列的方式、自组织性能和微结构,本文总结了Y型、T 型、O型、 K型、n型、螺旋桨型和哑铃型等不同形状分子的自组装行为,并展望了此类刚棒-线团分子未来研究的方向。

The rod-coil molecules, containing the hydrophilic poly(ethylene oxide) (PEO) chains and multi-phenylene as a rod, are able to self-assemble into various supramolecular nanostructures in bulk and an aqueous solution, caused by strong π-π stacking of aromatic rod segments and microphase separation of rod and coil segments. One of the great fascinating research topics is the creation of supramolecular nano-objects to explore novel properties and functions of rod-coil molecules. The shapes of the rod block can dramatically influence on the fashion of molecular arrangement, self-organizing property and micro-structure of rod-coil molecular system. In this paper, the self-assembling behaviors of diverse rod-coil molecules are summarized including Y-shaped, T-shaped, O-shaped, K-shaped, n-shaped, propeller-like and dumbbell-like rods. Finally, the future research trend of this kind of rod-coil molecules is prospected. Contents
