Electrolytic synthesis of porphyrinic Zr-metal–organic frameworks with selective crystal topologies

Abstract

The thermodynamic (PCN-222) and kinetic (PCN-224) products of porphyrinic Zr-metal–organic frameworks (MOFs) were synthesized via an anodic dissolution approach for the first time. To the best of our knowledge, this is the first report of MOF polymorphs being controlled by electrolysis. The selective formation of PCN-222 requires an amorphous component to be present on the electrode during the initial reaction process.
