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.
