Abstract

22,72,122,172-Tetra-tert-butyltetrabenzo-5,10,15-triazaporphyrine was synthesized, and its basic properties were studied by spectrophotometric titration. It was found that in the system ethanol-sulfuric acid nitrogen atoms in the tetrapyrrole macroring undergo protonation in three steps. The corresponding ionization constants and concentration ranges for mono-, di-, and tricationic forms of the examined compound were determined.
