Abstract  

The photoinduced valence isomerizations of three kinds of norbornadiene derivatives were performed under the sensitization of N-methylcarbazole. Fluoresecence quenching, chemically induced dynamic nuclear polarization (CIDNP) and thermodynamic discussion all support a mechanism involving electron transfer. The calculation of quantum yields indicates that the singlet electron transfer makes far more contributions to the photoisomerization than the triplet energy transfer. Additionally, the influence of solvent polarity on the photoisomerizations was also discussed.
