Transition metal-phosphine and -bipyridine complexes are ubiquitous in homogeneous catalysis due to the tunable steric and electronic properties of the ligands. Heterogeneous phosphine and bipyridine ligands have been developed using metal-organic frameworks (MOFs) as solid supports, but their assembly often relies on pre-functionalized linkers, which limits control of the MOF structure. This presentation will discuss our recent efforts to use postsynthetic modification to append phosphine and 2,2′-bipyridine ligands at the amine-functionalized linkers of mesoporous MOFs, such as MIL-101-NH<sub>2</sub>, and generate heterogeneous MOF catalysts via postsynthetic metalation. This approach yields precise control of ligand concentration and a well-defined microenvironment.
