Abstract Metalloporphyrinic metal–organic framework PCN-601 exhibits high photocatalytic performance for CO 2 reduction. The photoreduction site was speculated to be the Ni atoms in nodes and thus single porphyrin centers are not effectively utilized. In this study, we applied Kohn–Sham density functional theory investigate effect of metal (Fe, Co, or Cu) substitution Ni-porphyrin linker on Our...

Insertion of iron(II) into methylated derivatives of N-confused porphyrins 2-aza-2-methyl-5,10,15,20-tetraphenyl-21-carbaporphyrin (MeCTPPH)H, 2-aza-5,10,15,20-tetraphenyl-21-methyl-21-carbaporphyrin (CTPPMe)H2, and 2-aza-2-methyl-5,10,15,20-tetraphenyl-21-methyl-21-carbaporphyrin (MeCTPPMe)H yielded N- or C-methylated high-spin iron(II) complexes (MeCTPPH)Fe(II)Br, (HCTPPMe)Fe(II)Br, and (MeCT...

A new class of porphyrin array was synthesized. The Cu(II) porphyrin-PAMAM-Cu(II) porphyrin was obtained in good yields. The EPR studies showed that all porphyrins obtained have signals of a copper complex with planar geometry, and no variation in the tetrahedral distortion of the porphyrin ring was observed. The UV-vis and emission studies showed that the intensity of the signal increased due ...

The review focuses current research in the rapidly developing chemistry of porphyrin-fullerene complexes, and highlights recent advances in the synthesis, properties, and potential applications of this family. An overview of the most popular methods to prepare porphyrin complexes with C60 fullerene exhibiting various types of linkage is given with the main focus on the Prato reaction and its mo...

in this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (tnpp) and its zinc porphyrin complex (zntnpp) were synthesized in situ using the microwave method and identified by uv-vis, ft-ir and 1h nmr. the photostability and photodynamic antimicrobial activity (pact) of these compounds were investigated on pseudomonas aeruginosa and bacillus subtilis under visible light irradiation. mic, mbc an...

Significant tasks of the presented research are development multifunctional materials capable both to detect/capture carbon dioxide and monitor toxic metal ions from waters, thus contributing maintaining a sustainable clean environment. The purpose this work was synthesize, characterize (NMR, FT-IR, UV-Vis, Fluorescence, AFM) exploit optical emission properties carboxyl-substituted A3B porphyri...

The present study describes the first example of the hydroxylation of benzaldehydes by synthetic nonheme oxoiron(iv) complexes, where the reactivity, chemoselectivity, and mechanism were strongly influenced by the ligand environment of the iron center.

Mol-ecules of the title macrocycle, C(36)H(22)N(4)O(4), are located on an inversion center. The porphyrin ring shows a wave-like conformation with adjacent pyrrole rings tilted above the porphyrin plane and the inter-porphyrin distance is 3.584 (3) Å. The dihedral angles between the meso-furyl groups and the porphyrin plane are 38.87 (7) and 48.29 (7)°; these are much smaller than those observe...

A fullerene molecular tip was used to detect electron tunneling from a single porphyrin molecule. Electron tunneling was found to occur locally from an electron-donating moiety of the porphyrin to the fullerene through charge-transfer interaction between them. In addition, electron tunneling within the single fullerene-porphyrin pair exhibited rectifying behavior in which electrons can be drive...
