摘　　要：对笔者合成的不同结构与性能的聚苯胺因电子或极子跃迁而引起的可见 -近红外区的吸收特性进行了研究。详细讨论了掺杂聚苯胺分子构象对其光学吸收的影响。对该聚合物的染料增感作用研究发现 ,孔雀绿、酞菁铜和分散橙对于该聚合物均有增感作用 。A visible and near infrared absorption properties of various polyaniline(PAn) bases are studied, resulting from the transition of electrons and polarons. The effect of macromolecular conformation of emeraldine salt on the absorption spectra is discussed in detail. Investigation on dye sensitizing of the polymer reveals that malachite green, phthalocyanine and disperse orange are dopant for the polymer, they may enhance greatly the photoconductivity of polyaniline. Both phthalocyanine and malachite green are better dye sensitizing agent to polyaniline. Therefor, mixture of sensitive material is advantageous to the absorption of polyaniline in visible light spectrum.
