In this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-N,N´,N´´-trimethyl ammonium phenyl) porphyrin nickel(II) [Ni(II)(TF4TMAPP)]4+ is investigated in 5 mM aqueous phosphate buffer of pH 7.0 at 25.0 °C and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. The...
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...
A series of manganese and iron porphyrins with sterically protected pockets are shown to be shape selective alkane hydroxylation catalysts. With iodosobenzene as oxidant, good regioselectivity is observed for hydroxylation of alkanes at the least hindered methyl group by using the very sterically hindered (5,10,15,20-tetrakis(2’,4’,6’-triphenylphenyl)porphyrinato)manganese(III) acetate (MnTTPPP...
With the purpose of searching for new intriguing nanomaterial for spintronics, a series of novel metalloporphyrin nanowires (M-PPNW, M = Cr, Mn, Fe, Co, Ni, Cu and Zn) and hybrid nanowires fabricated by metalloporphyrin and metal-phthalocyanine (M-PCNW) are systematically investigated by means of first-principles calculations. Our results indicate that the transition metal atoms (TMs) embedded ...
