Saddling up copper - new twists on a metallo-wheel.
A unique octanuclear copper(II) cluster with a saddle-shaped structural topology has been prepared from a large, flexible polydentate ligand comprising a 4,4'-bipyridine linker bearing four pendant pyrazolate heterocycles.
متن کاملThe materials chemistry of porphyrins and metalloporphyrins
Porphyrins and metalloporphyrins provide an extremely versatile nanometer-sized building block for the control of materials properties. Films, solids and microporous solids have been explored as field-responsive materials (i.e. interactions with applied electric, magnetic or electromagnetic fields) and as ‘chemo-responsive’ materials (i.e. interactions with other chemical species as sensors or ...
متن کاملOpening Up the World of Chemistry
Not too long ago, we received an invitation from Wiley-VCH to be co-chairmen of a new open-access journal: ChemistryOpen. We had both previously received similar invitations to join the boards of other openaccess journals but declined these offers; however, after reading the letter from WileyVCH and knowing that numerous European Chemical Societies support the development of ChemistryOpen, it b...
متن کاملIron(III) Fluorinated Porphyrins: Greener Chemistry from Synthesis to Oxidative Catalysis Reactions.
Iron(III) fluorinated porphyrins play a central role in the biomimetics of heme enzymes and enable cleaner routes to the oxidation of organic compounds. The present work reports significant improvements in the eco-compatibility of the synthesis of 5,10,15,20-tetrakis-pentafluorophenylporphyrin (H₂TPFPP) and the corresponding iron complex [Fe(TPFPP)Cl], and the use of [Fe(TPFPP)Cl] as an oxidati...
متن کاملIntracellular trafficking of porphyrins.
Hemes are porphyrins that play a critical role in diverse biological processes. Heme synthesis culminates in the mitochondrial matrix, but the eight-step biosynthetic pathway is spatially shared between the mitochondria and cytoplasm. A recent paper describes the nature of the transporter that translocates the heme precursor coproporphyrinogen III into the mitochondria for heme synthesis. The i...
