本工作用循环伏安法研究了哒嗪的电化学氧化聚合过程以及聚哒嗪的电化学行为。合成了电导率约为1S/cm的聚哒嗪, 并采用光谱、能谱方法对它进行了表征。FTIR谱表明聚哒嗪中3,6-二取代哒嗪结构引起的吸收带位于1330, 1120, 1100和840cm^-^1, 掺杂聚哒嗪的双极子能带的两个光吸收峰分别位于1.8, 0.9eV。

Conducting polypyridazine with elec. conductivity of about 1S/cm was synthesized by electrochem. method. Cyclic voltammetry studies on pyridazine polymerisation and on the polymer film were carried out. The doping level of the as-grown polypyridazine with anion ClO4- was about 25%. In the FTIR spectra of polypyridazine, four absorption bands at 1330, 1120, 1100 and 840 cm-1 induced by 3, 6-disubstituted pyridazine structure were observed The doped polymer film has three optical absorption peaks at 0.9, 1.8, 3.4 eV, resp., and this indicates the evolution of bipolaron state in doped polypyridazine.
