Keeping MOM: Reaction of biphenyl-3,4′,5-tricarboxylate and Cd(NO3)2 in the presence of meso-tetra(N-methyl-4-pyridyl)porphine tetratosylate afforded porph@MOM-11, a microporous metal–organic material (MOM) that encapsulates cationic porphyrins and solvent in alternating open channels. Porph@MOM-11 has cation and anion binding sites that facilitate cooperative addition of inorganic salts (such as M+Cl−) in a stoichiometric fashion.
