Low‐Valent Metals in Metal‐Organic Frameworks Via Post‐Synthetic Modification

Abstract

Metal‐organic frameworks (MOFs) provide uniquely tunable, periodic platforms for site‐isolation of reactive low‐valent metal complexes of relevance in modern catalysis, adsorptive applications, and for fundamental structural studies. Strategies for integrating such species in MOFs include, post‐synthetic metalation, encapsulation and direct synthesis using low‐valent organometallic complexes as building blocks. These approaches have each proven effective in enhancing catalytic activity, modulating product distributions (i.e., by improving catalytic selectivity), and by providing valuable mechanistic insights. In this minireview, we explore these different strategies, as applied to isolate low‐valent species within MOFs, with a particular focus on examples that leverage the unique crystallinity, permanent porosity and chemical mutability of MOFs, to achieve deep structural insights that lead to new paradigms in the field of hybrid catalysis.
