摘要：

Femtosecond time-resolved absorption spectroscopy measurements were performed on polydiacetylene 15-8 and polydiacetylene p-toluene sulfonate. The relaxation of the singlet exciton was measured to be a two-component process with an initial relaxation in ∼95 fs followed by complete recovery in ∼1.5 ps. The rapid formation of broadband photoinduced absorption was observed with recovery in a few picoseconds.
