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 2 –MoS 2 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 2 sheets. Therefore, this straightforward approach gives access to the controlled connection of sulfide‐based 2D materials.
