Leveraging Exchange Kinetics for the Synthesis of Atomically Precise Porous Catalysts Academic Article uri icon

abstract

  • AbstractMetalorganic frameworks (MOFs) have attracted significant attention as porous catalyst platforms due to the synthetic modularity of these materials and the diversity of latticeconfined catalytic active sites that are readily embedded within periodic crystalline frameworks. MOFs offer platforms to heterogenize molecular catalysts, stabilize novel coordination motifs, and leverage confinement effects in catalysis. Crystallinity allows diffractionbased methods to be employed in the characterization of these catalysts. Access to crystalline MOFs typically requires reversible construction of the metalligand (ML) bonds that connect the SBUs, which provides a mechanism to anneal defects during crystallization. While the required ML bond reversibility is often promoted by synthesis at elevated temperature, access to crystalline materials based on either transition metals with characteristic slow exchange kinetics or highly basic donor ligands remains a synthetic challenge. Here, we highlight synthetic strategies that leverage ML exchange kinetics to access MOFs based on kinetically inert ions and extensions of these strategies to the assembly of atomically precise multimetallic materials.
