, p. 2993 - 2996 (1997)
The synthesis of meso-tetraarylporphyrines bearing 1-4 catechoylamid groups was achieved. Among the four new compounds prepared, the structure of the disubstituted ligand was elucidated in the solid state by an X-ray analysis.

, p. 5853 - 5856 (2013)
The first direct synthesis of A3-type unsymmetrical porphyrin is achieved via conventional pyrrole-aldehyde condensation in a one-pot procedure in an appreciable yield. Generalization of this approach to a variety of other aldehydes revealed th

Photodynamic therapy (PDT) is a noninvasive therapeutic and promising procedure in cancer treatment and has attracted considerable attention in recent years. In the present paper, 2-piperidinetetraphenylporphyrin derivatives (P1–P3) conjugated with differ
Thiaporphyrins with one, two and four unsubstituted meso-carbons: Synthesis and functionalization
Agarwal, Neeraj,Hung,Ravikanth
, p. 3730 - 3734 (2003)
Thiaporphyrins with one, two and four unsubstituted meso carbons were synthesized from easily available thiophene diols. The reactivity at these carbons was demonstrated by carrying out series of reactions and some very useful functional groups were introduced. ( Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003).
Novel fullerene receptors based on calixarene-porphyrin conjugates
Ká?, Martin,Lang, Kamil,Stibor, Ivan,Lhoták, Pavel
, p. 477 - 481 (2007)
Several different synthetic approaches enabling a direct covalent connection between the meso-position of porphyrin and the upper rim of calix[4]arene have been studied. The best results were obtained via condensation of an excess of pyrrole and p-methylb
Cobalt Porphyrin-Polypyridyl Surface Coatings for Photoelectrosynthetic Hydrogen Production
Beiler,Khusnutdinova,Wadsworth,Moore
, p. 12178 - 12185 (2017)
Hybrid materials that link light capture and conversion technologies with the ability to drive reductive chemical transformations are attractive as components in photoelectrosynthetic cells. We show that thin-film polypyridine surface coatings provide a molecular interface to assemble cobalt porphyrin catalysts for hydrogen evolution onto a visible-light-absorbing p-type gallium phosphide semiconductor. Spectroscopic techniques, including grazing angle attenuated total reflection Fourier transform infrared spectroscopy, confirm that the cobalt centers of the porphyrin macrocycles coordinate to pyridyl nitrogen sites of the organic surface coating. The cobalt porphyrin surface concentration and fraction of pyridyl sites coordinated to a cobalt center are quantified using complementary methods of ellipsometry, inductively coupled plasma mass spectrometry, and X-ray photoelectron spectroscopy. In aqueous solutions under simulated solar illumination the modified cathode is photochemically active for hydrogen production, generating the product gas with near-unity Faradaic efficiency at a rate of ≈10 μL min-1 cm-2 when studied in a three-electrode configuration and polarized at the equilibrium potential of the H+/H2 couple. This equates to a photoelectrochemical hydrogen evolution reaction activity of 17.6 H2 molecules s-1 Co-1, the highest value reported to date for a molecular-modified semiconductor. Key features of the functionalized photocathode include (1) the relative ease of synthetic preparation made possible by application of an organic surface coating that provides molecular recognition sites for immobilizing the cobalt porphyrin complexes at the semiconductor surface and (2) the use of visible light to drive cathodic fuel-forming reactions in aqueous solutions with no added organic acids or sacrificial chemical reductants.
