To construct an interface between a π-conjugated organic molecule and an inorganic/metal surface, 5,10,15,20-tetrakis[4-(5-hydroxypentyloxy)phenyl] porphyrin was chemisorbed on silica gel by refluxing in pyridine. Thermogravimetric analysis confirmed that
Convenient synthetic route of versatile 21-monothiatetraphenylporphyrins of the A4 and AB3 type

, p. 2907 - 2912 (2005)
A novel convenient synthetic route for poly-functional 21- monothiatetraphenylporphyrins of the type A4 und AB3 having base labile substituents in meso position was developed. Using this method a series of symmetric and asymmetric 21-thiaporphyrins containing different functional groups at the meso position is reported. The new products were characterized by NMR, UV-Vis and mass spectroscopy.
Optimized synthesis of tetrakis(4-methoxyphenyl)porphin-Co(II)

Detailed kinetic investigation of Rothemund synthesis of porphyrins was conducted in different solvents. A one-pot synthesis of tetrakis(4- methoxyphenyl)porphin-Co(II) from pyrrole, anisic aldehyde, and cobalt acetate was developed that gave 35% isolated yield. Chlorobenzene was found to be the best solvent for the reaction. The synthesis can be done with either propionic or chloroacetic acid as catalyst with about the same yield. Cobalt prevents the synthesis of the porphyrin, so it has to be added in the reaction mixture only after the synthesis of the free porphyrin is finished. Optimum time is 2-2.5h at a temperature of 130C. Lower temperatures reduce the yield. Potentially, these dependencies can be applied to synthesis of other analogous porphyrins.

Hydroxyalkyloxy substituted tetraphenylporphyrins: Mechanism and superoxide scavenging activity
Kuzmin, Sergey M.,Chulovskaya, Svetlana A.,Parfenyuk, Vladimir I.
, p. 1477 - 1485 (2016)
The novel electrochemical approach based on coulometric response of electro-generated superoxide (O2?-) was used to determine scavenging properties of 2H-5,10,15,20-tetrakis (4-hydroxyphenyl)porphyrin (H2T(4-OHPh)P); 2H-5,
Expression of Fas antigen and apoptosis caused by 5,10,15,20-tetra(4-methoxyphenyl)porphyrin (TMP) on carcinoma cells: implication for photodynamic therapy

, p. 69 - 74 (2000)
The photodynamic effects of 5,10,15,20-tetra(4-methoxyphenyl)porphyrin (TMP) on a Hep-2 cell line were investigated. TMP toxicity in the dark and in relation to illumination with visible light was examined. Hep-2 cells were treated with different TMP conc
Substituent and solvent effects on the hyperporphyrin spectra of diprotonated tetraphenylporphyrins

, p. 3486 - 3496 (2003)
UV-visible spectra was studied for a series of p-substituted tetraphenylporphyrins (TPP) titrated with strong acid in various solvents. The longest wavelength absorption at 811 nm, however, was the greatest shift for any diprotonated substituted TPP. The magnitude of the shift was enhanced by a solvent effect. Diprotonated TAPP could be observed 10 fluoresce weakly in dichloromethane (DCM) solvent but not in dimethyl sulfoxide. DCM, which light exposure in the presence of a poryphyrin generated sufficient acid to significantly affect the spectrum. The effect was noted quantitatively by placing a dilute (4μM) TTP solution in a diode array spectrophotometer; an effective acid titration could be observed simply by exposing the sample to the monitoring beam over a period of 2 min.
