O. Bartels et al., Photooxidation of cyclopentadiene by artificial and solar light irradiation with dissolved and immobilized photosensitizers, J INF REC, 25(3-4), 2000, pp. 251-258
1,3-Cyclopentadiene can be photooxidized efficiently by irradiation with vi
sible light using 2,9,16,23-tetrasulfophthalocyanines with various central-
metal-ions as photosensitizers. The used photosensitizers were also immobil
ized on the cationic ion exchanger Amberlite IRA-400 and examined as hetero
geneous photosensitizer. These immobilized photosensitizers can be easily s
eparated from the reaction mixture.
