Synthetic two-dimensional polymers (2DPs) are an emerging subclass of 2D materials that are accessible by mild and rational synthesis procedures. Because of their structure, which is reminiscent of a molecular fisherman’s net, 2DPs strongly differ from conventional linear polymers. They are expected to show applications in fields such as gas separation, nonlinear optics, and miniaturization of optical devices. The article sketches the historic development that led to the first fully proven representatives, describing each case in detail and comparing the current main access routes. Insights into some application aspects are also given. Alternative synthesis routes are also presented, together with the critical analytical issues. Structure analysis is perhaps the greatest challenge in this field, which arises with regard to proving the periodic structure of a 2DP. This article intends to stimulate the interest of an interdisciplinary community to join forces to develop this promising field even more quickl...

合成二维聚合物

合成二维聚合物 (2DP) 是新兴的二维材料子类，可通过温和合理的合成程序获得。由于其结构让人想起分子渔夫网，2DP 与传统的线性聚合物有很大不同。预计它们将在气体分离、非线性光学和光学器件小型化等领域展示应用。文章概述了导致第一个经过充分验证的代表的历史发展，详细描述了每个案例并比较了当前的主要访问路线。还给出了一些应用方面的见解。还介绍了替代合成路线以及关键的分析问题。结构分析可能是这个领域最大的挑战，这是在证明 2DP 的周期结构时出现的。本文旨在激发跨学科社区的兴趣，联合起来更快地开发这个有前途的领域……
