Synthesis and Characterization of Phosphine-Functionalized Metal–Organic Frameworks Based on MOF‑5 and MIL-101 Topologies

Phosphine metal–organic frameworks (P-MOFs) are an emerging class of coordination polymers that provide novel opportunities for metal–supported catalysis as solid ligands. Here, we present the synthesis and characterization of three novel P-MOFs based on a (diphenylphosphino)­terephthalic acid linker. We targeted the structures of MOF-5, MIL-101­(Cr), and MIL-101­(Al)-NH2 to produce materials with partial diphenylphosphine substitution, which were crystalline and highly porous.
