چکیده

The diverse e4orts to rationally construct microporous solids using porphyrins and metalloporphyrins as molecular building blocks are reviewed. Porphyrin-based molecular crystals, hydrogen-bonded networks, and metal ion coordination polymer networks are examined in detail. Recurring geometrical motifs observed in the structural frameworks of di4erent porphyrinic solids are emphasized, and the in6uences of solvates and guest molecules are explored. Attempts to construct porphyrin+ siloxane networks are also reviewed. ( 2000 Academic Press

A functional zeolite analogue assembled from metalloporphyrins.

The assembly of molecular building blocks with metal ions generating microporous network solids has been the focus of intense activity. Because of their potential applications associated with channels and cavities, such materials have been examined for size- and shape-selective catalysis, separations, sensors, molecular recognition and nanoscale reactors. Within this context, assemblies of robu...

A catalytically active, permanently microporous MOF with metalloporphyrin struts.

Through the use of the tetratopic ligand 1,2,4,5-tetrakis(4-carboxyphenyl)benzene as a key building block, a permanently microporous metal-organic framework with Lewis acidic (porphyrin)Zn struts, ZnPO-MOF, can be made in high yields. ZnPO-MOF can efficiently catalyze acyl-transfer reactions primarily by preconcentrating the substrates within its pores, in stark contrast to analogous supramolec...

Synthesis of metalloporphyrin-based conjugated microporous polymer spheres directed by bipyridine-type ligands.

Zinc porphyrin (TP-Zn)-based conjugated microporous polymer (Zn-CMP) spheres were obtained via Sonagashira-Hagihara cross coupling reactions between 5,10,15,20-tetrakis(4-ethynylphenyl)porphyrin-Zn(II) and brominated monomers directed by bidentate bipyridine (BP)-type ligands for the first time, and the sphere diameters could be adjusted from 320 to 740 nm. The coordination between BP and TP-Zn...

A robust microporous zinc porphyrin framework solid.

A robust microporous zinc(II) metalloporphyrin framework solid has been synthesized. The proposed structural model developed from X-ray single crystal data has an interpenetrated three-dimensional framework of zinc trans-biscarboxylate tetraarylporphyrins whose carboxylates coordinate the six edges of tetrahedral Zn(4)O(6+) clusters, maintaining a charge-neutral framework. This cubic framework ...

A three-dimensional microporous metal-metalloporphyrin framework.

A new porphyrin-based microporous MOF, {Mn(II)0.5[Mn(II)4Cl(Mn(III)Cl-ttzpp)2(H2O)4]}·(DEF)20·(CH3OH)18·(H2O)12 (UTSA-57), has been constructed from {5,10,15,20-tetrakis[4-(2,3,4,5-tetrazolyl)phenyl]porphyrinato} manganese(III) chloride as the metalloligand. The MOF adopts the rare scu topology with one-dimensional square nanotube-like channels of about 20 Å. UTSA-57a exhibits permanent porosit...
