摘　　要：观测了聚苯胺(PAn)在不同状态(掺杂、反掺杂、碱式、氧化、还原)下的拉曼光谱.根据其光谱特性,结合其它实验结果,提出了掺杂态PAn分子链包含电荷分布不等的三种苦环和二种氮原子的四单元苯醌变体模型,指出质子酸掺杂系分子内氧化还原反应,讨论了PAn氧化程度对掺杂效率的影响.Resonance Raman spectra of polyaniline (PAn) in different forms (base, doped, dedoped, reduced and oxidized) were determined. According to the spectral features and other experimental results, it was found that the molecular chain of the doped PAn consists of two kinds of N atoms and three kinds of aromatic rings with different charge distribution. The effect of the oxidation extent of the PAn chain on the doping efficiency was observed. Thus the 'Four-ring BQ derivatives' model and corresponding doping reactions were proposed.
