聚邻甲基苯胺的顺磁共振光谱

THE ELECTRON SPIN RESONANCE OF POLY(O-METHYL)ANILINE

聚邻甲苯胺Ⅰ和聚邻甲基苯胺Ⅱ在 0 5mol/LNH4Cl+ 1mol/LZnCl2 溶液中的电极电位分别为 + 0 2 70V和 - 0 2 30V(VS SCE) ,结果表明 ,它们的顺磁共振谱仅由单一的狭窄线组成 ,没有发现超精细结构。聚邻甲基苯胺Ⅰ的g因子为2 0 0 31 ,聚邻甲苯胺Ⅱ的g因子为 2 0 0 32 ,这表明聚邻甲苯胺在氧化还原过程中 ,电子结构没有发生变化。

The electrode potenials of poly(o-methyl) aniline Ⅰ and Ⅱ were +0 270V and -0 230V(VS SCE),respectively,in the aqueous solution containing 1 0mol/L ZnCl 2+0 5mol/L NH 4Cl.Their ESR Spectra consisted of a single narrow line without the observation of hyperfine structure in the spectra.The g factors of poly(o-methyl) aniline Ⅰ and Ⅱ were 2 0031 and 2 0032,respectively.This indicated that the electron structure of Poly(o-methyl) aniline did not change during the redox processes.On the basis of our results,it has also been vertified that poly (o-methyl) aniline is a very stable polymer with free radicals.
