Conclusions

  1. A dependence of the magnetic resonance parameters on the nature of the anion was established for organic polythiophene conductors with various anions.
  2. The major values of the anisotropic g-tensor were measured by 2-mm band ESR spectroscopy and the conductivity of polythiophene (BF4 – and polyacetylene (I) was evaluated at 200°K.
