摘　　要：本文通过对不同条件下的Co(W_2O_7)_6^(10-)和CuW_(12)O_(40)^(6-)掺杂聚吡膜ESR谱线的分析并以相同条件下NO_3^-掺杂聚吡咯膜作为参照,表明杂聚阴离子不仅起着中和电性的作用,而且与聚吡咯分子链相作用形成某种加合物,它影响聚吡咯的电结构,这种加合物在过正或过负的电位下均不稳定.首次发现在CuW_(12)O_(40)^(6-)掺杂的干态聚吡咯膜具有Dysonian线型,表明膜中其它电结构的存在.The ESR of PPy films doped with Co (W2O7)610- and CuW12O406- ions were reported and discussed. Results show that heteropolyanions not only play the role of neutralizing electricity in the PPy film, but also interact with the PPy molecular chain to form some adducts. The adducts affect the electronic structure of the PPy film and are unstable at more positive or more negative potentials. Dysonian ESR lineshape was recorded for the dry PPy film with CuW12O406-for the first time.
