Abstract
Femtosecond transient absorption spectra of a quasi-one-dimensional halogen -bridged mixed-valence metal complex [Pt(en)(2)]Pt(en)(2)Cl-2] (PF6)(4) hav e been measured. It has been found that the neutral solitons are generated from charge transfer excitons within the time resoution (300fsec). It is fo und that charged solitons are generated by the interband excitation. The ri se time and decay time of the charged soliton absorption band are 2.2psec a nd 6.5psec respectively.
