Effect of Chemical Modification of the Tetrapyrrole Macrocycle Structure on the Spectral, Acid–Base, and Complexing Properties of tert-Butyl-Substituted Porphyrazines

Abstract

The effect of chemical modification of the tetrapyrrole macrocycle structure on the spectral, acid–base, and complexing properties of tetrakis[5,6-bis(4-tert-butylphenyl)pyrazino]porphyrazine, tetra(4-tert-butyl)phthalocyanine, and octakis(4-tert-butylphenyl)porphyrazine in acetonitrile at 298–318 K has been studied by 1H NMR, electronic spectroscopy, and mass spectrometry. The obtained results can be used in the design of macrocyclic tetrapyrrole functional materials with desired physicochemical properties.
