Porous Salts as Platforms for Heterogeneous Catalysis (Small 30/2023)

Porous Salts In article number 2207507, Eric D. Bloch and co-workers present a novel approach toward constructing reactive, porous solids. The porous salt, built upon an anionic cage balanced by a cationic chromium(II) complex, is successfully characterized using a plethora of spectroscopic techniques and single crystal X-ray diffraction (XRD). The site-isolated chromium(II) centers readily activate dioxygen in the solid state, producing chromium(III)-superoxide, demonstrating increased stability while retaining C-H activation capabilities.
