Abstract

Steady-state and transient fluorescence measurements have been made using mixtures of 9,10-dichloroanthracene and 2,5-dimethyl-2,4-hexadiene in benzene and acetonitrile. In benzene a fluorescent exciplex, λmax ∼485 nm, τ 7.4 nsec, forms reversibly with an estimated equilibrium constant for exciplex formation at room temperature of 20 ± 1 M-1. In contrast, no exciplex fluorescence is observed from acetonitrile solutions at intermediate diene concentrations, but triplex fluorescence λmax ∼543 nm and τ 3.6 nsec, is observed at higher diene concentrations. Steady-state fluorescence observations in the presence of air are also described.
