摘要：

Fluorescence quenching of the pyrene-NN-dimethylaniline exciplex with water pools of various size constructed in inverted micelles is studied by an emission-absorption laser photolysis method. Only the triplet state of pyrene is observed as a transient species. The rate of enhanced intersystem crossing due to exciplex quenching depends on the size of the water pools and is reduced by external magnetic fields. The quenching dynamics of exciplexes in inverted micellar solutions are discussed.
