【 摘 要 】

Various spectroscopic data for doped conjugated polymers are reviewed and discussed. Chemical doping induces polaron states in the conjugated polymers. Two polaron states appear between the π and π∗states. Third harmonic generation spectroscopy reveals the multiply-resonant nonlinear optical processes using the polaron states. The terahertz measurements clarify the carrier localization, which is dependent on the doping levels. The ultrafast luminescence measurements reveal the relaxation process of the photoexcited states of the doped conjugated polymers.
