摘要

手性不仅广泛存在于各类天然物质和生物体系中，同时也是人工合成高分子的重要结构特征之一. 高分子中的手性结构包括分子、分子链、聚集态等多个层级，而嵌段共聚物的微相分离为手性信息的跨层级传递和表达提供了一条途径. 在本文中，我们综述了有关嵌段共聚物本体手性自组装的研究报道. 首先简要介绍了高分子中不同层级手性结构的表征方法，之后对嵌段共聚物中2种手性相(螺旋相、手性螺旋二十四面体)的形成规律、结构特征及潜在应用进行了总结，最后提出了嵌段共聚物本体手性自组装研究中存在的问题和挑战.

Abstract

Chirality plays a significant role not only in various natural substances and biological systems but also as a critical structural feature in synthetic polymers. In polymers

hierarchical chirality encompasses molecular chirality

conformational chirality

and object chirality. The microphase separation of block copolymers offers a pathway for the cross-level transfer and expression of chiral bias. This review provides an overview of recent studies on the chiral self-assembly of block copolymers in bulk. It begins with a brief introduction to the methods used for characterizing chiral structures across different levels. The review then discusses the fo

rmation mechanisms

structural characteristics

and potential applications of two types of chiral self-assemblies in block copolymers

i.e.

helical phase and chiral double gyroid. Finally

the challenges and open questions in the study of chirality transfer in block copolymers are addressed.
