“…The reduction process in dichloromethane (CH 2 Cl 2 ) occurs at −1.03 V, −1.35 V and the oxidation process takes place at 1.13 V, 1.37 V. These processes should be the porphyrins ring redox processes because p-CH 3 TPP does not contain other constituents that can be reduced or oxidized. As reported in the literature [29][30][31][32], factors affecting stability of the ionic forms of the macrocyclic compounds, (both cationic and anionic), yielded by proton transfer are electronic factors (or polarization), structural (or steric), and solvation factors.…”

“…Porphyrins are usually subdivided into classical (with moderate distortion of the planarity of the macrocycle and well-known properties), and nonclassical (with nontraditional structures and properties) [29]. The lightly nonplanarity of p-methyl meso-tetraphenylporphyrins makes the NH centers more accessible to an attack of a base or a deprotonation.…”

A series of aluminium(III)-p-methyl-meso-tetraphenylporphyrin (p-CH3TPP-Al(III)) containing axially coordinated salicylate anion [p-CH3TPP-Al-X)], where X = salicylate (SA), 4-chlorosalicylate (4-CSA), 5-chlorosalicylate (5-CSA), 5-flourosalicylate (5-FSA), 4-aminosalicylate (4-ASA), 5-aminosalicylate (5-ASA), 5-nitrosalicylate (5-NSA), and 5-sulfosalicylate (5-SSA), have been synthesized and characterized by various spectroscopic techniques including ultraviolet-visible (UV-vis), infrared (IR) spectroscopy, proton nuclear magnetic resonance (1H NMR) spectroscopy,13C NMR, and elemental analysis. A detailed study of electrochemistry of all the synthesized compounds has been done to compare their oxidation and reduction mechanisms and to explain the effect of axial coordination on their redox properties.

meso-Aryltetrabenzoporphyrins. Synthesis and properties

2008

View full text Add to dashboard Cite

The most considerable achievements in the synthesis and investigations of meso aryl tetrabenzoporphyrins and their metal complexes are reviewed. The choice of the route to, and the properties of, these compounds depends on the nature and number of meso aryl substituents. The reviewed synthetic methods are compared. Selected physicochemical and spectroscopic properties of meso aryltetrabenzoporphyrins are analyzed.
