摘要：

For the amorphous pellet of Cu-phthalocyanine with bulky substituents photoexcitation energy relaxation processes and their polarization-dependent dynamics were measured and analyzed by picosecond regular reflection spectroscopy. The triplet state (T-1) decayed upon T-1-T-1 annihilation, and the vibrationally hot ground state was produced by ultrafast photothermal conversion via the annihilation. On the basis of depolarization dynamics, the migration of the T-1 state is concluded to occur slightly in 20 ps and the annihilation takes place in molecules of the close vicinity.
