Аннотация:The acid doping process of the mixtures of
N,N′-diphenyl-1,4-phenylenediamine (DPPD) and N,N′-diphenyl-1,4-quinonediimine
(DPQD), reduced and oxidized
phenyl-capped aniline dimers respectively, has been studied in
detail by UV−vis−NIR and ESR spectroscopies. The addition
of the acid to the mixtures of DPPD and DPQD leads to the
formation of one type of radicals by intermolecular
interactions. Full conversion of the aniline dimer molecules
to the radical form is achievable only in stoichiometric mixtures
of DPPD and DPQD. Concentration of radical species may
change over time according to processes involving hydrolysis. The mechanisms of the acid doping of the phenyl-capped dimer
process and subsequent side processes are proposed.
