【Abstract】 Poly(N,N-dimethylaniline)(PDMA) is a novel πconjugated polymer of polyphenylene derivative, which has some unique properties due to its strong donor side groups. This paper first described the structure characteristics of PDMA’s cation radicals, then studied the effects of temperature and solution viscosity on its delocalized radicals in detail. It is found that the conformation changes of main chains and side chains on PDMA are both related to its radical stability. 更多还原
