摘要：

The picosecond photoinduced absorption of a series of alpha-coupled thiophene oligomers in solution have been measured using the Kerr ellipsometry configuration. We present spectral and dynamic studies of the sharp transient absorption peak observed in the transparency region of these oligomers. Its origin and the reasons for its narrow line shape are discussed. The conversion towards the triplet state is observed in terthiophene.
