摘要: 提出了一条合成还原态的苯基封端聚苯胺齐聚物的新方法:即苯胺二聚体的Schiff碱或苯胺三聚体的Schiff碱在酸性溶液中缓慢水解,形成聚苯胺二聚体和三聚体的盐酸盐,这些盐酸盐与二苯胺或N-苯基-对苯二胺反应,经苯肼还原,生成还原态的苯基封端的聚苯胺三聚体和四聚体.用红外、核磁、元素分析和基底辅助激光解吸质谱对其进行了表征,并用紫外光谱对还原态的三聚体和四聚体的化学氧化过程进行了跟踪研究.

Abstract: Phenylcapped trianiline and tetraaniline in the leucoemeraldine oxidation state were synthesized through a modified-pseudo-high-dilution technique. The chemical oxidation process of these compounds were studied by UV-Vi s spectra. It was found that phenyl-capped trianiline in the leucoemeraldine oxidation state was oxidized to its EBform and then decomposed. Phenyl-capped tetraaniline was oxidized to its EBform and then to the pernigraniline oxidation state.

Key words: Polyaniline, Oxidative coupling reaction, Oligomers, UV-V is spectra
