Selective preparation of two-dimensional polymers (2DPs) and supramolecular polymers (2DSPs) with defined thickness is crucially important for controlling and maximizing their functions, yet it has remained as a synthetic challenge. In the past decade, several approaches have been developed to allow selective preparation of discrete monolayer 2DPs and 2DSPs. Recently, crystal exfoliation and self-assembly strategies have been employed to successfully prepare bilayer 2DP and 2DSP, which represent the first step towards the controlled "growth" of 2D polymers from the thinnest monolayers to thicker few-layers along the third dimension. This Concept review discusses the concept of accurate synthesis of 2D polymers with defined layers. Advances in this research area will pave the way to rational synthetic strategies for 2D polymers with controlled thickness.
选择性制备具有明确厚度的二维聚合物（2DPs）和超分子聚合物（2DSPs）对于控制和最大化其功能至关重要，但这仍然是一个合成挑战。在过去的十年中，已经开发出几种方法来允许选择性制备离散的单层 2DPs 和 2DSPs。最近，晶体剥离和自组装策略已被用于成功制备双层 2DP 和 2DSP，这代表了朝着沿着第三维从最薄的单层到更厚的少数层控制“生长”二维聚合物的第一步。这篇概念综述讨论了具有明确层的二维聚合物的精确合成概念。这一研究领域的进展将为具有可控厚度的二维聚合物的合理合成策略铺平道路。
