Solid-state supramolecular chemistry of porphyrins. Hydrogen-bonded networks and porous crystals ofmeso-tetra[4-(3,5-diaminotriazino)phenyl]porphyrin

Metalloporphyrin Molecular Sieves

“…The resulting molecularsieve structure occupies only 39 % of the crystal volume and contains 1.5 nm wide (at the narrowest point) channels propagating through the crystal. [22] These assemblies mutually interpenetrate with each other and yield a spectacular concatenated arrangement sustained in three dimensions by cooperative hydrogen bonding (every porphyrin unit takes part in sixteen hydrogen bonds). While these crystals deteriorate slowly when left in an open air (loosing the solvent), they are quite stable when covered with a very thin layer of light oil.…”

“…Indeed, the correspondingly functionalized porphyrin moiety TDTPP (6), has been successfully applied to the construction of a uniquely structured solid that consists of flat multiporphyrin networks with unprecedently large voids, 2.2 Â 2.2 nm 2 . [22] These assemblies mutually interpenetrate with each other and yield a spectacular concatenated arrangement sustained in three dimensions by cooperative hydrogen bonding (every porphyrin unit takes part in sixteen hydrogen bonds). The resulting architecture is quite stable below 80 8C.…”

Photoinduced Processes of Supramolecular Nanoarrays Composed of Porphyrin and Benzo[ghi]perylenetriimide Units through Triple Hydrogen Bonds with One‐Dimensional Columnar Phases

“…To form the 2,4-diamino-1,3,5-triazinyl group from the nitrile group, ar eaction of C 12 -H 2 P-CN and dicyandiamidew as performed. [16] Finally,C 12 -ZnP was obtained by introducing zinc to the center of the porphyrin ring. Detailsoft he synthetic procedure and characterization are shown in the Experimental Section.…”

62 Porphyrin-Based Tectons in Molecular Tectonics

“…3.0 Å). 137 This tecton offers 16 NH donor and 12 N acceptor sites. Each tecton is involved in 16 H-bonds and connected to six adjacent porphyrins.…”
