Study of acidic-basic properties of aminoazo-compounds obtained from poly- p-aminophenylacetylene

Six aminoazo-compounds were synthesized from poly- p-aminophenylacetylene. Using absorption spectra in the visible range a study was made of acidic-basic properties of the aminoazo-compounds in solutions of alcohol, DMSO or DMF. It was found that the aminoazo-compounds in acidic solutions form catio...

Description
Summary:Six aminoazo-compounds were synthesized from poly- p-aminophenylacetylene. Using absorption spectra in the visible range a study was made of acidic-basic properties of the aminoazo-compounds in solutions of alcohol, DMSO or DMF. It was found that the aminoazo-compounds in acidic solutions form cations of azo- or quinonehydrazone structure and in the presence of alkaline agents in aprotic polar solvents (DMSO and DMF) can behave as weak NH-acids (p K ≈ 19), forming corresponding mesomeric anions.
