摘要：

Characteristic absorption of the anion radical of pyromellitimide around 715 nm was demonstrated to be particularly useful for studies on photoinduced electron transfer reactions. Charge recombination in pyromellitimide-linked porphyrin was greatly retarded in benzene due to the large energy gap and small reorganization energy. A long-lived charge separated state (tau = 2.5-mu-s) was formed in the case of a diporphyrin-porphyrin-pyromellitimide triad system.
