Structure of K-Doped Polyacetylene and Its Variations with Annealing, Studied by Neutron Diffraction
It was found recently that annealing cis-polyaeetylene[(CH)x] doped with potassium, at temperatures higher than 140°C, produces a large permanent increase in its room temperature d.c. conductivity by a factor of 5–10 (Fig. 1). The annealed films are remarkably stable even at temperatures as high as 200°C (1).A somewhat smaller effect was observed on Rb-doped samples, whereas Li-doped, Na-doped and Cs-doped cis-(CH)x did not show any substantial conductivity increase upon annealing (1). This behavior of n-doped (CH)x contrasts sharply with that of the p-doped samples, which degrade quickly and irreversibly upon even a modest increase of temperature (2).
