Synthesis and Properties of Fe Complexes with Deuteroporphyrin and Hematoporphyrin

摘要

Deuteroporphyrin and hematoporphyrin as complete methyl esters and their complexes with iron(III) were synthesized and characterized by NMR and electronic spectroscopy. For the first time the changes of the specific heat capacity of these solid biological objects with temperature were investigated by the method of differential scanning calorimetry. These parameters are shown to be smooth functions of temperature in the range 290-360 K, indicating the absence of the phase transitions in these systems.
