Metal–Organic Frameworks: Scalable Room‐Temperature Conversion of Copper(II) Hydroxide into HKUST‐1 (Cu₃(btc)₂) (Adv. Mater. 7/2013)

The back cover illustrates scanning electron micrographs of copper(II) hydroxide (elongated crystals) and HKUST-1 (octahedral crystals). Javier Pérez-Ramírez and Gerardo Majano demonstrate on page 1052 a sustainable and scalable route to quantitatively converting an insoluble layered hydroxide into the pure metal-organic framework (MOF) with the highest reported productivities. This simple and low-cost synthesis is expected to bring an expanded use of this MOF in laboratory investigations and in industrial scenarios.
