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(<i>N</i>-methyl-4-pyridyl) porphine cations to afford three metalloporphyrin-encapsulating metal–organic materials, <b>porph@MOM-11</b>, <b>-12</b> and <b>-13</b>, 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. <b>Porph@MOM-12</b> is noteworthy because it exhibits two distinct types of hexagonal channels and it represents the first example of a net that exhibits <b>mzz</b> topology
