摘要：
We succeeded in polymerization of a n-type conjugated polymer, poly(pyridopyrazinevinylene). Its properties of nonlinear opticalabsorption and carrier dynamics of the excited states have been investigated by using picosecond time-resolved pump-probe spectroscopy. Optical bleaching and reverse saturable absorption were observed in the wavelength region above and below the bandgap, respectively. These results could be explained in terms of five-state model with three singlet and two triplet states.
