Triplet quantum yield determination by photosensitized oxygenation in the presence of heavy atom additives: Rhodamine B in methanol

Autor: Theodor Franken, Mohamed F.R. Fouda, Klaus Gollnick

Publikováno v: Tetrahedron Letters. 22:4049-4052

Relative rates of heavy-atom-enhanced photosensitized 1O2-reactions may be used to determine φoT of sensitizers in heavy-atom-free solutions. φoT = 0.12 ± 0.02 is obtained for a 5·10−5 M methanolic solution of Rhodamine B .
