Abstract :
The formation and decay processes of triplet polyphenyl compounds (3PPC∗: p-terphenyl, trimethylbenzene and triphenylene) sensitized by triplet benzophenone (3BP∗) were investigated by laser photolysis techniques at 295 K. The net rate constant and efficiency for the formation of 3PPC∗ were obtained. The deactivation pathway of 3PPC∗ was found to proceed via triplet exciplexes since the decay rate of 3PPC∗ as a function of [BP] gave a negative curve. The kinetic parameters for the triplet exciplex were determined.
