Photosensitized Reduction of Methylviologen through the Energy Transfer from Triplet Dyes to 9-Anthracenecarboxylate Anion

The reaction mechanism for photosensitized reduction of methylviologen, MV2+ through the triplet–triplet energy transfer from organic dyes to 9-anthracenecarboxylate, AC− was investigated. From the kinetic analysis on MV\underset.+ formation, it was estimated that both efficiencies of the energy tra...

Summary:The reaction mechanism for photosensitized reduction of methylviologen, MV2+ through the triplet–triplet energy transfer from organic dyes to 9-anthracenecarboxylate, AC− was investigated. From the kinetic analysis on MV\underset.+ formation, it was estimated that both efficiencies of the energy transfer and of the electron transfer from 3AC− to MV2+ were close to unity.
