Two-dimensional polymers (2DPs), comprising mono- or multilayer covalent polymeric networks with long-range order in two orthogonal directions, are of considerable interest due to their unique physicochemical properties. However, achieving precise thickness control from monolayer to bilayer, crucial for exploring proximity effect-driven phenomena beyond the monolayer limit, remains synthetically challenging. Here we report the on-water surface synthesis of crystalline mechanically interlocked monolayer and bilayer 2DP (MI-M2DP and MI-B2DP) films by embedding macrocyclic molecules with one and two cavities into 2DP backbones. The incorporation of bulky macrocyclic molecules introduces periodic mechanical bonds that precisely control interlayer interlocking, enabling selective monolayer or bilayer 2DP formation. Both MI-M2DP and MI-B2DP exhibit homogeneous, large-area films with ordered hexagonal pores and high modulus. MI-B2DP demonstrates an exceptionally high effective Young’s modulus of 151 ± 16 GPa (indentation method), surpassing MI-M2DP (90 ± 14 GPa), van der Waals-stacked MI-M2DPs (46 ± 11 GPa) and other reported multilayer 2DPs (<50 GPa). Modelling confirms that the mechanical interlocking minimizes interlayer sliding and reinforces the structure.
二维聚合物（2DPs），由单层或多层共价聚合物网络组成，在两个正交方向上具有长程有序，由于其独特的物理化学性质而引起了相当大的兴趣。然而，实现从单层到双层的精确厚度控制，对于探索超越单层极限的接近效应驱动现象至关重要，在合成上仍然具有挑战性。在这里，我们报道了通过在2DP骨架中嵌入具有一个和两个空腔的大环分子，在水表面合成晶体机械互锁单层和双层2DP （MI-M2DP和MI-B2DP）薄膜。庞大的大环分子的结合引入了周期性的机械键，精确地控制层间联锁，使选择性单层或双层2DP形成。MI-M2DP和MI-B2DP均表现出均匀、大面积的薄膜，具有有序的六方孔和高模量。MI-B2DP的有效杨氏模量高达151±16 GPa（压痕法），超过了MI-M2DP（90±14 GPa）、van der waals堆叠MI-M2DP（46±11 GPa）和其他已报道的多层2dp （50 GPa）。模型证实，机械联锁最小化层间滑动和加强结构。
