title: Pillared porphyrin homologous series: intergrowth in metal-organic frameworks.
abstract: We report three new porphyrin-based, pillared paddle-wheel homologous series: porphyrin paddle-wheel frameworks PPF-3, -4, and -5. These compounds are assembled from free base or palladium tetrakis(4-carboxyphenyl)porphine, M(NO(3))(2) (M = Co and Zn), and 4,4'-bipyridine via solvothermal reactions. The resulting solids exhibit 3D metal-organic frameworks, where 2D layers are pillared by bipyridine with three different packing arrangements.
