The photochemicalbehaviour of octafluoronaphthalenetowardsconjugateddienes is shown to exhibit a pronounced solvent dependence which is explained in terms of the formation of exciplexes in non-polar solvents and solvated charge-transfer complexes or ion pairs in polar solvents.

which involves the intermediacy of a diene cationradical generated by transfer of an electron from the adsorbed diene to a photogenerated hole localized at the surface of the excited TiO2 particle. Non-oxidative cleavage products are also observed, and the effect of the semiconductor surface in controlling reactivity of the photogenerated cationradical is discussed. The first examples of aromatization
Diene triplets in predominantly the s-cis conformation are formed efficiently by back electron transfer to dienecationradicals in DMF and dichloromethane.
