Templated Synthesis, Postsynthetic Metal Exchange, and Properties of a Porphyrin-Encapsulating Metal–Organic Material

Reaction of biphenyl-3,4′,5-tricarboxylate (H3BPT) and CdCl2 in the presence of meso-tetra­(N-methyl-4-pyridyl)­porphine tetratosylate (TMPyP) afforded porph@MOM-10, a microporous metal–organic material containing CdTMPyP cations encapsulated in an anionic Cd­(II) carboxylate framework, [Cd6(BPT)4Cl4(H2O)4]. Porph@MOM-10 is a versatile platform that undergoes exchange to serve as the parent of a series of porph@MOMs that exhibit permanent porosity and heterogeneous catalytic activity.
