Conclusions
-
1.
The rate constants of quenching of the triplet state of benzanthrone and phenazine by substituted N,Ndimethylanilines, anilines, and phenols in n-heptane and CH3CN were determined by the method of flash photolysis.
-
2.
The capacity of quenching agents to deactivate the triplet state in heptane at the same ionization potential increases as the acidity increases in the order N,N-dimethylanilines > anilines > phenols.
-
3.
Total electron transfer is the most probable mechanism of quenching by N,N-dimethylanilines. Quenching by anilines and phenols is due to intercombination conversion in an exciplex with charge transfer and hydrogen bonding.
