摘要：

Polypyrrole films have been prepared that contain counteranions derived from stable free radicals, i.e. 1,3,5-triphenylverdazyl (TPV) sulfonic acid or Frémy's salt. These polymer films as well as different crystalline molecular TPV derivatives have been characterized by ESR, static magnetic susceptibility and electrical conductivity measurements. Sizable (antiferromagnetic) exchange coupling is observed with asymptotic Curie temperatures amounting to - 12 K < θ{symbol}p < -6 K for only the large spin concentrations achieved for TPV and its derivatives. © 1990.
