In the last decade, the development of thin-layer organic 2D materials has attracted considerable attention due to their unique properties arising from 2D planar structures and versatility of organic chemistry. Several synthetic strategies have been developed to synthesize organic 2D materials, such as 2D polymers, 2D supramolecular polymers as well as single/thin-layer 2D covalent organic frameworks and metal-organic frameworks, either by top-down exfoliation or bottom-up interfacial synthesis methods. Among these, the liquid interface offers a flat and uniform surface for a 2D confinement which renders the preparation of organic 2D materials on a large area under ambient conditions. This review article summarizes the recent developments on the interfacial synthesis of single-layer and few-layer organic 2D materials involving polymerization at the air-water interface by the Langmuir-Blodgett method and at liquid-liquid interfaces. Insights into the perspectives and challenges of synthetic strategies as well as structural characterization are provided for the future development of organic 2D materials.
在过去十年中，薄层有机二维材料的发展因其二维平面结构产生的独特性质以及有机化学的多功能性而备受关注。已经开发了几种合成策略来合成有机二维材料，例如二维聚合物、二维超分子聚合物以及单/薄层二维共价有机框架和金属有机框架，可通过自上而下的剥离或自下而上的界面合成方法来实现。其中，液体界面为二维限制提供了一个平坦且均匀的表面，这使得在环境条件下大面积制备有机二维材料成为可能。这篇综述文章总结了单层和少层有机二维材料界面合成的最新进展，包括通过朗缪尔-布洛杰特方法在气-水界面以及在液-液界面进行的聚合反应。针对有机二维材料的未来发展，提供了对合成策略以及结构表征的前景和挑战的见解。
