Abstract

Two-dimensional layered structural materials exhibit a wide range of properties due to their ultrahigh specific surface area. However, achieving ordered exfoliation to obtain uniform two-dimensional structures remains challenging. In this study, we developed a supramolecular system by covalently bonding hexathiobenzene (HB) into β-cyclodextrin to create a light-responsive moiety, followed by coassembly with bipyridine and nickel ions to form a polypseudorotaxane (PR) system, which enables an in situ light-induced exfoliation strategy for two-dimensional materials. By further introducing an appropriate ratio of ethanol and applying in situ light irradiation, the gradual evaporation of the solvent ultimately led to the uniform formation of bilayer PR two-dimensional materials. This strategy provides a novel and effective approach for the preparation of two-dimensional layered structural materials from the light perspective.

聚聚环氧紫杉烷纳米片的有序光剥

二维层状结构材料由于其超高的比表面积而表现出广泛的性能。然而，实现有序剥离以获得均匀的二维结构仍然具有挑战性。在这项研究中，我们开发了一种超分子体系，通过共价键将六硫苯（HB）与β-环糊精结合，形成光响应部分，然后与联吡啶和镍离子共组装形成聚聚环氧紫杉烷（PR）体系，从而实现二维材料的原位光诱导剥离策略。通过进一步引入适当比例的乙醇并施加原位光照射，溶剂的逐渐蒸发最终导致双层PR二维材料的均匀形成。该策略从光的角度为二维层状结构材料的制备提供了一种新颖有效的方法。

期刊介绍： ACS Macro Letters publishes research in all areas of contemporary soft matter science in which macromolecules play a key role, including nanotechnology, self-assembly, supramolecular chemistry, biomaterials, energy generation and storage, and renewable/sustainable materials. Submissions to ACS Macro Letters should justify clearly the rapid disclosure of the key elements of the study. The scope of the journal includes high-impact research of broad interest in all areas of polymer science and engineering, including cross-disciplinary research that interfaces with polymer science. With the launch of ACS Macro Letters, all Communications that were formerly published in Macromolecules and Biomacromolecules will be published as Letters in ACS Macro Letters.
