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.

苯酚封端的苯胺二聚体的酸掺杂:分子间极化子形成机理及其对聚苯胺的适用性。

NN'-二苯基-1,4-苯二胺(DPPD)和NN'-二苯基-1,4-喹烯二胺(DPQD),还原的和氧化的苯基封端的苯胺二聚体混合物的酸掺杂过程,已经通过紫外可见近红外和ESR光谱学进行了详细研究。将酸添加到DPPD和DPQD的混合物中导致通过分子间相互作用形成一种类型的自由基。仅在DPPD和DPQD的化学计量混合物中,才能将苯胺二聚体分子完全转化为自由基形式。自由基物质的浓度可能会根据涉及水解的过程随时间变化。提出了苯基封端的二聚体过程和随后的副过程中酸掺杂的机理。
