The combination of 2D materials opens a wide range of possibilities to create new‐generation structures with multiple applications. Covalently cross‐linked approaches are a ground‐breaking strategy for the formation of homo or heterostructures made by design. However, the covalent assembly of transition metal dichalcogenides flakes is relatively underexplored. Here, a simple covalent cross‐linking method to build 2H‐MoS₂–MoS₂ homostructures is described, using commercially available bismaleimides. These assemblies are mainly connected vertically, basal plane to basal plane, creating specific molecular sized spaces between MoS₂ sheets. Therefore, this straightforward approach gives access to the controlled connection of sulfide‐based 2D materials.

2H-MoS2纳米片的共价交联

二维材料的组合为创建具有多种应用的新一代结构提供了广泛的可能性。共价交联方法是突破性的策略，可通过设计形成同构或异构结构。然而，过渡金属二卤化物薄片的共价组装相对未充分研究。在此，描述了使用市售双马来酰亚胺构建2H-MoS ₂ -MoS ₂同质结构的简单共价交联方法。这些组件主要在垂直方向上连接基平面和基平面，从而在MoS ₂薄板之间创建特定的分子大小的空间。因此，这种简单的方法可以访问基于硫化物的2D材料的受控连接。
