The results show that during the protonic acid doping, a partial redox reaction takes place between the quinone-diimine and benzene-diamine units and it leads to a long conjugate system with a certain charge distribution.展开更多

文摘The chain structure of polyaniline doped with HCl or CF_3COOH has been investigated by FTIR, solid state ^(13)CNMR, resonance laser Raman and UV-VIS spectroscopies. The results show that during the protonic acid doping, a partial redox reaction takes place between the quinone-diimine and benzene-diamine units and it leads to a long conjugate system with a certain charge distribution.
