Bottom-Up Assembly of Amorphous Metal-Organic Frameworks From Proton Conductive Metal-Organic Polyhedra. [PDF]
SmallStructural control in amorphous MOFs (aMOFs) remains challenging compared to their crystalline counterparts. We report a bottom‐up strategy using metal‐organic polyhedra as predefined building units. By crosslinking these clusters, we preserve intrinsic node functionality within aMOFs, achieving proton conductivity up to 4.8 mS cm−1 at 85°C and 90% RH,
