Conclusions

The rate constants were measured for the annihilation of the triplet exciplexes of quinones with 4-phenylaniline in various solvents and the prototropic equilibrium constants in the primary exciplex were also determined. Hydrogen bonding between the radicals in the exciplex leads to an acceleration of radiationless deactivation of the exciplex to the ground state and retardation of the dissociation of the exciplexes into radical-ions. The solvation of the exciplexes of an alcohol is accompanied by a decrease in the rate of deactivation of the exciplexes to the ground state.
