Cover Picture: Mechanochemical Synthesis of Boroxine‐linked Covalent Organic Frameworks (Angew. Chem. Int. Ed. 51/2024)

Mechanochemistry can be used in the synthesis of covalent organic frameworks (COFs), as reported by Xavier Ottenwaelder, Tomislav Friščić, Dmytro F. Perepichka et al. in their Research Article (e202404539). Based on this concept the first mechanochemical synthesis of boroxine-based 2D and 3D COFs with high surface area of up to 2,500 m2 g−1 was developed. The cover picture shows the structure of the monomers and the COF with the electron micrograph of the mechanochemically prepared COF in the background.
