A molybdenum crown cluster forms discrete inorganic-organic nanocomposites with metalloporphyrins

Filled doughnuts: Molybdenum crown cluster MC accommodates up to three molecules of aminophenyl-substituted metalloporphyrins through hydrogen-bonding interactions, to form discrete inorganic-organic nanocomposite materials (see picture; blue polyhedra = MC, space-filling model = metalloporphyrin). Ultrahigh-vacuum scanning tunneling microscopy, in conjunction with scanning tunneling spectroscopy, at 80 K confirms the formation of the inclusion complex. (Figure presented).

Covalent functionalization and solubilization of multi-walled carbon nanotubes by using zinc and copper complexes of meso-tetra(4-aminophenyl) porphyrin

Zinc (II) and copper (II) complexes of mesotetra(4-aminophenyl)porphyrin (Zn-TAP and Cu-TAP) were covalently connected to multi-walled carbon nanotube (MWCNT) through an amide linkage and characterized by using many spectroscopic techniques. Significant m

Synthesis method of tetra (4-aminophenyl) porphyrin metal complex

The invention discloses a synthesis method of a tetra (4-aminophenyl) porphyrin metal complex. The method comprises the following steps: 1) taking organic acid as a solvent and pyrrole and 4-halogen benzaldehyde as substrates, and carrying out condensation reaction to obtain a (4-halogen phenyl) porphyrin solid; 2) dissolving the (4-halogen phenyl) porphyrin solid in an organic solvent, adding a metal salt, and reacting to obtain a (4-halogen phenyl) porphyrin metal complex; and 3) taking the (4-halophenyl) porphyrin metal complex and ammonia water as substrates, and carrying out carbon-nitrogen coupling reaction in the presence of a catalyst and an organic solvent to obtain the tetra (4-aminophenyl) porphyrin metal complex. The method is mild in reaction condition, low in toxicity, green and environment-friendly.

Intrinsic Activity of Metal Centers in Metal-Nitrogen-Carbon Single-Atom Catalysts for Hydrogen Peroxide Synthesis

Metal-nitrogen-carbon (M-N-C) single-atom catalysts (SACs) show high catalytic activity for many important chemical reactions. However, an understanding of their intrinsic catalytic activity remains ambiguous because of the lack of well-defined atomic str

Systematic selection of metalloporphyrin-based catalysts for oxygen reduction by modulation of the donor-acceptor intermolecular hardness

Incisive modulation of the intermolecular hardness between metalloporphyrins and O2 can lead to the identification of promising catalysts for oxygen reduction. The dependency of the electrocatalytic reduction of O2 by metalloporphyrins on the nature of the central metal yields a volcano-type curve, which is rationalized to be in accordance with the Sabatier principle by using an approximation of the electrophilicity of the complexes. By using electrochemical and UV/Vis data, the influence of a selection of meso-substituents on the change in the energy for the π→π* excitation of manganese porphyrins was evaluated allowing one to quantitatively correlate the influence of the various ligands on the electrocatalysis of O2 reduction by the complexes. A manganese porphyrin was identified that electrocatalyzes the reduction of oxygen at low overpotentials without generating hydrogen peroxide. The activity of the complex became remarkably enhanced upon its pyrolysis at 650 °C. Finding the strength: Incisive modulation of the intermolecular hardness between metalloporphyrins and O2 can lead to the identification of promising catalysts for the oxygen reduction reaction (see figure). The feasibility of this principle is demonstrated in the selection and design of a manganese metalloporphyrin with promising high activity for electrocatalytic oxygen reduction. Copyright
