Abstract

The topological resonance energy (TRE) model was used to study the aromatic stability of cationic AH+ and anhydrobase from A of the flavylium chromophoric system. The calculated values of TRE are within the regular limits for the aromatic molecules, with the cationic forms being more aromatic than the anhydrobase forms. Higher stability of 4-CH3 flavylium salts is expected relative to 4-H flavylium salts.
