摘　　要：介绍了聚（Ｎ，Ｎ－二甲基苯胺）阳离子自由基的结构特点，利用顺磁共振波谱和紫外－可见吸收光谱，研究了温度及溶液粘度对聚合物自由基的影响，发现聚（Ｎ，Ｎ－二甲基苯胺）的主、侧链结构构象变化与其自由基的稳定性有很大的关系。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. 
