摘要：

We report on sub-10 femtosecond time-resolved optical dynamics in polycarbazolyldiacetylene blended in a polyethylene matrix which is a prototype of single chain systems. Transmission difference data reveal an ultrafast kinetics which is assigned to the rapid internal conversion taking place following photoexcitation. Oscillations in the time-dependent traces are assigned to impulsive stimulated resonant Raman scattering, based on the comparison with cw Raman data. (C) 2001 Elsevier Science B.V.
