The electrochemical behavior of free-radical derivatives of tetra(4hydroxyl-3,5-di-tert-butylphenyl) porphyrins and their complexes with Mg(II), Zn(II), Ni(II), CU(II), and Pd(II) ions was studied by the methods of voltamperometry, ESR, and spectrophotometry. It was shown that the introduction of free-radical substituents into the porphin macrocycle leads to a substantial decrease in the oxidation and reduction potentials of the complexes. The degree of conjunction of substituents with the porphin macrocycle is estimated according to the difference of the redox potentials of free-radical and quinoid derivatives of metalloporphyrins.
