Abstract

Model systems for heme were constructed using three different compounds. The tetrasulfophthalocyanine transition metal derivatives were studied and rejected due to problems with the purification procedure. Transition metal derivatives of tetrapyridyl porphine were studied and rejected due to problems in the synthesis and low concentrations of the chemical in solution. Finally, the transition metal derivatives of tetraphenyl porphine were studied and spectral data were obtained. The spectral data indicate that Fe(II)TPP is stable in the presence of oxygen. A photochemical reaction does occur, however, which appears to change the Fe(II)TPP to Fe(III)TPP. Other facts were also found. The ZnTPP is found to undergo a photochemical reaction similar to the one for Fe(II)TPP. The MnTPP appears to have already changed oxidation state upon synthesis. The data suggest that TPP is a possible system for studying the interaction of heme and oxygen. The TPyP system might be even better if the problems with synthesis could be solved since its water solubility should solve the problem due to a low concentration.
