Electrochemical reduction of CO2 to valuable products on molecular catalysts draws attention due their versatile structures allowing tuning activity and selectivity. Here, we investigate temperature influence conversion product selectivity over a Cobalt(II)-tetraphenyl porphyrin (CoTPP)/multiwalled carbon nanotube (MWCNT) composite in the range 20–50 ?. Faradaic efficiency changes with potentia...

During the last few years, porphyrins and metalloporphyrins have attracted widespread attention as chromophores for studies in circular dichroism (CD), an indispensable chiroptical tool for monitoring chiral interactions. This review summarizes the multifaceted properties of porphyrins and metalloporphyrins, powerful CD chromophores that are characterized by their intense and red-shifted Soret ...

The preparation of fullerene complexes with metal tetraarylporphyrins in the presence of excess ferrocene (Cp(2)Fe) results in the formation of new solvent-free and multicomponent molecular crystals. New isomorphous complexes of C(60) with PyZnTPP (ZnTPP identical with zinc 5,10,15,20-tetraphenyl-21H,23H-porphyrinate) and PyCoTPP (CoTPP identical with cobalt(II) 5,10,15,20-tetraphenyl-21H,23H-p...

A technique for preparing heterobimetallic frameworks with tunable metal sites is demonstrated by the synthesis of a new two-dimensional metal-organic framework that is constructed from tetra(4-carboxyphenyl)porphyrin and Cd(II) species. The solid can be prepared in the presence of other divalent transition metals to yield the same framework with the smaller metal ions occupying the porphyrin l...

A combined chemical/chiroptical microscale protocol for the determination of absolute configurations of cyclic alpha-hydroxyketones is described. The hydroxyl group in cyclic alpha-hydroxyketones is converted into (3-aminopropylamino)acetate (NH2CH2CH2CH2NHCH2COOR), or more generally, according to a newly developed protocol, into (3-hydroxypropylamino)acetate group (HOCH2CH2CH2NHCH2COOR). The r...

The coverage-dependent self-assembly of Nickel-tetraphenyl porphyins on Gold vicinal surfaces was studied by scanning tunneling microscopy. On Au(788) the molecular is square-shaped, following symmetry. Au(332) molecules nucleate in a parallelogram lattice for monolayer coverage and squared multilayer coverage. Depending surface adopt either saddle shaped or more planar conformation. experiment...

Thin organic films are widely used in sensors, solar cells, and optical devices due to their intense absorption the visible/near-infrared (IR) region. Shifting, quenching, or reshaping of some spectral features can be achieved by chemical functionalization molecules, whereas an anisotropic fingerprint preferential molecular alignment induced via a proper design and/or preparation substrate.
