Three porphyrin-encapsulating metal-organic materials with ordered metalloporphyrin moieties

1,3,5-benzenetricarboxylate, biphenyl-3,4′,5-tricarboxylate, and [1,1′:3′,1″-terphenyl]-4,4″,5′-tricarboxylate react with Cd(II) cations in the presence of meso-tetra(N-methyl-4-pyridyl) porphine cations to afford three metalloporphyrin-encapsulating metal-organic materials, porph@MOM-11, -12 and -13, respectively. The metalloporphyrin moieties are ordered within channels and closely fit hexagonal or rectangular cavities, thereby facilitating a better understanding of the structure-directing effect that can be promoted by metalloporphyrins. Porph@MOM-12 is noteworthy because it exhibits two distinct types of hexagonal channels and it represents the first example of a net that exhibits mzz topology.
