Conclusions
-
1.
Quenching of the chloranil triplet state by methylated benzenes in nonpolar solvents leads to the formation of short-lived triplet exciplexes whose structure depends on the oxidation potential of the donor. An increase in the electron donor capacity of the quencher is accompanied by an increase in the contribution of a state with complete charge transfer to the structure of the triplet exciplex.
-
2.
The equilibrium constants for the formation of triplet exciplexes between chloranil in the triplet state and methylated benzenes were determined.
