- Abstract
- Electron transfer photochemistry starting from a twisted intramolecular charge transfer (TICT) excited state is shown, using N-(alpha-naphthyl)carbazole (NC) as sensitizer. The NC TICT state has been used as electron donor and acceptor. This dual reactivity is demonstrated by fluorescence quenching measurements, and the rate constants have been correlated with the help of the Marcus equation. Photochemical reactions have also been performed. Photoisomerization of the quadricyclane into norbornadiene is proof of the radical cationic reactivity of the TICT, while photodechlorination of pentachlorobenzene is proof of radical anionic reactivity. A triplet sensitized ring closure of norbornadiene was also shown to occur.
