Electronic properties of non-doped and doped polyacetylene films studied by E.S.R.

摘要

Cis-polyacetylene films have been synthetized and doped with iodine and antimony penta fluoride, using usual chemical techniques. Doping, leads, after saturation, to conductivity values of about 120 and 25 (Ω cm) -1 at room temperature, respectively for I2 and SbF 5 dopants. The E.S.R. of cis- and trans-, non-doped and doped (CH)x films has been studied. A qualitative analysis of the results allows a better understanding of the electronic properties of these extremely non homogeneous and highly conductive doped polymeric materials.
