Description
Summary:After synthesis, poly(seleno- p-arylene diamine) has been doped with chlorine. X-ray photoelectron spectroscopy (XPS) and electron spin resonance (ESR) have been carried out on the doped powder. The changes in the experimental results with storage time have been systematically analyzed. It is observed that, relative to carbon, the atomic percentage of oxygen increases with time while the signals of N, Cl and Se decrease. The changes in the N1s and Se3d spectra show that the polymer is progressively decomposed by chlorine. This decomposition is in good agreement with the change in the ESR signal. These modifications can explain the decrease in conductivity with increasing storage time.
