NOVEL REACTIVITY OF PHOTOEXCITED IRON PORPHYRINS CAGED INTO A POLYFLUORO SULFONATED MEMBRANE IN CATALYTIC HYDROCARBON OXYGENATION

Heterogenization of iron porphyrins inside Nafion creates new photocat alytic systems which can be used to oxidize cyclohexene and cyclohexan e with sunlight and O-2 under mild conditions (room temperature, atmos pheric pressure); the polymeric matrix makes the iron porphyrin a good photocatalyst for the monooxygenation of the substrate and increases both its photocatalytic efficiency (about ten times) and its stability (turnover values > 1000).
