Double‐helical nanostructures with controllable handedness in bulk materials is of high interest in science and technology for the design and fabrication of new materials, in particular metamaterials, which mimic their natural homologues or even show superior properties. Herein, we report the fabrication of double‐helical structures with controlled handedness through the self‐assembly of an achiral diblock copolymer doped with d‐ and l‐tartaric acid (TA). The helices showed clear handedness dependence on the chirality of the TA. The chiral arrangement of different achiral tectonic units, such as nanoparticles and organic molecules, was confirmed using this helical structure as a template. The double‐helical structure will provide new knowledge for understanding the function of helices, and will enable the application of these systems as chiroptical materials.

块状二嵌段共聚物中具有可控手性的双螺旋纳米结构

散装材料中具有可控操纵性的双螺旋纳米结构在科学技术中对设计和制造新材料（特别是模仿其天然同系物甚至表现出优异性能的超材料）特别感兴趣。本文中，我们报告了通过掺杂了d和l的非手性二嵌段共聚物的自组装，制备了具有可控手性的双螺旋结构。酒石酸（TA）。螺旋线显示出明显的上手性取决于TA的手性。使用这种螺旋结构作为模板，可以确认不同的非手性构造单元（例如纳米粒子和有机分子）的手性排列。双螺旋结构将为理解螺旋的功能提供新的知识，并将使这些系统能够用作按摩材料。
