Synthesis of Binuclear Copper (II) Complexes with Expanded Porphyrins
The synthesis and characterization of some new binuclear copper (II) complexes, based on the use of large, pyrole-containing macrocycles, the so called "expanded porphyrins", [Cu2(macrocycle)]+4 is described. Electron Spin Resonance (ESR) studies indicate a weak "half-field line", which is characteristic of the Cu(II)-Cu(II) dimer, is observed at about 1600G. The obser...
متن کاملSynthesis of amphiphilic graphene nanoplatelets.
Graphene, a flat monolayer of carbon atoms tightly packed into a two-dimensional honeycomb lattice, has attracted a great deal of attention in recent years for potential applications in many technological fields, such as nanoelectronics, nanocomposites, and hydrogen supercapacitors. One possible route to harnessing these properties would be to incorporate graphene sheets into composite material...
متن کاملThe Enzymatic Synthesis of Porphyrins from Porphobilinogen.
The partial purification of porphobilinogen deaminase from spinach leaf tissue and some details of the action of this enzyme in the synthesis of uroporphyrinogen I, have been reported in earlier communications (2-5). Uroporphyrin I has been found in nature in the escreta of humans and other animals under certain pathological conditions (6, 7). The arrangement of the propionic and acetic acid si...
متن کاملSynthesis and characterization of azobenzene-confined porphyrins.
A versatile synthetic method has been developed to incorporate photochromic azobenzene moieties into tetraphenylporphyrin frameworks in an orthogonal fashion, positioning the phenylazo substituents above and below the plane of the macrocycle. Surprisingly, photoisomerization is completely suppressed in the resulting azobenzene-confined porphyrins.
متن کاملInterfacial assemblies of atypical amphiphilic porphyrins: hydrophobicity/hydrophilicity of substituents, annealing effects, and supramolecular chirality.
Interfacial molecular assemblies of eight atypical amphiphilic porphyrins, substituted with hydrophobic or hydrophilic substituents but without long alkyl chains on their molecular skeletons, have been investigated in terms of supramolecular chiralty generation and amplification. It is found that all of the originally organized interfacial molecular assemblies display very weak or undetectable ...
