β¦ Synopsis
In an attempt to understand conductivity enhancement at a microscopic scale, the electrically conducting complex of poly(Schiff base sulphide)/I 2 has been studied by XPS, ESR and FT-IR as well as electrical conductivity measurements. Results showed that charge-transfer complex between PSBS and iodine will be formed, yielding radical-cations (polarons) and dications (bipolarons) on the polymer chain and I-, I; or 15 counteranions. Transformation of polaron to bipolaron was observed. The structural changes of the polymer induced by doping are discussed.

Electron spin resonance (ESR) and d.c. conductivity measurements on iodine-doped poly(Nvinylcarbazole) (PVK) as a function of annealing treatment was performed. When doped at room temperature as at 370 K, the appearance of an ESR signal and the increase of the conductivity can be explained by CT com
