Synthetic chemists have developed robust methods to synthesize discrete molecules, linear and branched polymers, and disordered cross-linked networks. However, two-dimensional polymers (2DPs) prepared from designed monomers have been long missing from these capabilities, both as objects of chemical synthesis and in nature. Recently, new polymerization strategies and characterization methods have enabled the unambiguous realization of covalently linked macromolecular sheets. Here we review 2DPs and 2D polymerization methods. Three predominant 2D polymerization strategies have emerged to date, which produce 2DPs either as monolayers or multilayer assemblies. We discuss the fundamental understanding and scope of each of these approaches, including: the bond-forming reactions used, the synthetic diversity of 2DPs prepared, their multilayer stacking behaviors, nanoscale and mesoscale structures, and macroscale morphologies. Additionally, we describe the analytical tools currently available to characterize 2DPs in their various isolated forms. Finally, we review emergent 2DP properties and the potential applications of planar macromolecules. Throughout, we highlight achievements in 2D polymerization and identify opportunities for continued study.

二维聚合物和聚合

合成化学家已经开发出可靠的方法来合成离散分子、线性和支化聚合物以及无序交联网络。然而,从设计的单体制备的二维聚合物 (2DP) 长期以来一直缺乏这些能力,无论是作为化学合成的对象还是在自然界中。最近,新的聚合策略和表征方法能够明确实现共价连接的大分子片层。在这里,我们回顾了 2DP 和 2D 聚合方法。迄今为止,已经出现了三种主要的 2D 聚合策略,它们以单层或多层组件的形式生产 2DP。我们讨论了每种方法的基本理解和范围,包括:使用的成键反应、制备的 2DP 的合成多样性、它们的多层堆叠行为、纳米尺度和中尺度结构以及宏观形态。此外,我们描述了目前可用于以各种孤立形式表征 2DP 的分析工具。最后,我们回顾了新兴的 2DP 特性和平面大分子的潜在应用。在整个过程中,我们重点介绍了 2D 聚合方面的成就,并确定了继续研究的机会。
