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-MoS -MoS homostructures is described, using commercially available bismaleimides. These assemblies are mainly connected vertically, basal plane to basal plane, creating specific molecular sized spaces between MoS sheets. Therefore, this straightforward approach gives access to the controlled connection of sulfide-based 2D materials.
二维材料的组合为创建具有多种应用的新一代结构开辟了广泛的可能性。共价交联方法是通过设计形成均相或异质结构的开创性策略。然而，过渡金属二硫属化物薄片的共价组装相对较少被探索。在此，描述了一种使用市售双马来酰亚胺构建2H-MoS₂-MoS₂同质结构的简单共价交联方法。这些组装体主要是垂直连接，基面与基面相连，在MoS₂片层之间形成特定分子大小的空间。因此，这种直接的方法能够实现硫化物基二维材料的可控连接。
