采用不同种类质子酸对聚邻甲苯胺进行掺杂,发现质子酸的酸性、分子尺寸和氧化性均不同程度地影响其掺杂率和电导率.大分子尺寸有机强酸掺杂可诱导掺杂态聚合物的溶解性.ESR测量结果表明,中性聚邻甲苯胺的自旋电子主要定域在杂原子上;质子酸掺杂导致氮原子上的电子产生重新组态,并部分离城到邻近的芳环上,显示出芳香π-电子的特性.电阻与压力依赖性研究揭示出质子酸掺杂聚邻甲苯胺的导电类型为电子型.
Doping of poly-o-toluidine with different kinds of proton acids showed that acidity, molecular size and oxidation of proton acids all affected their doping rate and conductivity to different extents.Molecular sizes of organic acid doping induced doping states Solubility of the polymer. The ESR measurements show that the spinodal electrons of the neutral poly-o-toluidine are mainly localized on the heteroatoms; the proton acid doping causes the electron generation on the nitrogen atoms to reconfigure and partially exit the neighbors to the vicinity Of the aromatic ring, showing the aromatic π-electron properties.Resistance and pressure dependence of the proton acid-doped poly-o-toluidine revealed that the conductivity type of electronic type.
