Metalloporphyrin Molecular Sieves
Chemistry – A European Journal, 2000Crystal-engineering strategies have been systematically developed for the rational design by self-assembly of diverse metalloporphyrin molecular-sieve materials. Cooperative coordination and hydrogen bonding algorithms of molecular recognition proved particularly useful for this aim.

Hydrogen Generation by Hangman Metalloporphyrins
Journal of the American Chemical Society, 2011A cobalt(II) hangman porphyrin with a xanthene backbone and a carboxylic acid hanging group catalyzes the electrochemical production of hydrogen from benzoic and tosic acid in acetonitrile solutions. We show that Co(II)H is exclusively involved in the generation of H(2) from weak acids.

Vibronic Transitions in Single Metalloporphyrins
ChemPhysChem, 2005AbstractStructural and electronic properties of single zinc etioporphyrin molecules adsorbed on Al2O3/NiAl(110) were probed by a low‐temperature scanning tunneling microscope (STM). Scanning tunneling spectroscopy (STS) revealed progressions of spectral features corresponding to the vibronic states of individual molecules that depend strongly on the ...

The first phosphite complex of a metalloporphyrin
Acta Crystallographica Section C Crystal Structure Communications, 2003(Diphenyl phosphite-kappaO)(5,10,15,20-tetraphenylporphyrinato-kappa(4)N)manganese(III) hexafluoroantimonate(V), [Mn(C(44)H(28)N(4))(C(12)H(11)O(3)P)](SbF(6)), is the first example of a structurally characterized diaryl or dialkyl phosphite complex of a metal-porphyrin ion.

Out-of-plane metalloporphyrin complexes
Journal of Chemical Education, 1975Abstract : Recent progress in the chemistry of synthetic metalloporphyrins has shown that the porphyrin moiety can act as a bi-, tri- or hexadentate ligand, as well as the usual tetradentate ligand. In addition, the metal ion has been observed to possess 4, 5, 6 or 8-coordination.

Metalloporphyrin Dendrimers with Folding Arms
Angewandte Chemie International Edition, 1998Rigid and flexible linkers are combined in the new dendrimer shown schematically in the picture, which contains nine metalloporphyrin units (Porph). The construction is such that the four "arms" of the dendrimer can fold in a cooperative and predetermined manner in response to added 1,4-diazabicyclo[2.2.2]octane (DABCO).

Homo- and heterodimer formation in metalloporphyrins
Inorganic Chemistry, 1985On a obtenu les constantes de formation des dimeres de CuP, AgP et VOP dans le chloroforme par mesures RPE a temperature ambiante et simulation spectrale. P=l'ester dimethylique de la mesoporphyrine IX. On a aussi fait des mesures dans le tetrachloro-1,1,2,2ethane et le dichloromethane pour CuP.

Peroxynitrite scavenging by metalloporphyrins and thiolates
Free Radical Biology and Medicine, 2000The rate constant for the reaction of nitric oxide with superoxide virtually assures that peroxynitrite will be formed to some extent in any cell or tissue where both radicals exist simultaneously. The precise biological targets for peroxynitrite and the nature of the modification of those targets vary dramatically depending on their relative ...

Metalloporphyrins for the treatment of neonatal jaundice
Current Opinion in Pediatrics, 2005To evaluate the safety and efficacy of metalloporphyrins for the treatment of neonatal hyperbilirubinemia.Since the 1980s and 1990s, there have been no publications on trials to determine the efficacy of metalloporphyrins in the treatment of neonatal jaundice.
