Аннотация:AbstractThe work examines the possibilities of generating optically inaccessible exciplexes by radiation chemistry techniques and describing them using quantum chemical methods. Two new target compounds were synthesized, and their luminescent properties were characterized. Using radiation-induced luminescence methods, the formation of exciplexes with N,N-dimethylaniline from these compounds as a result of recombination of a radical ion pair in a nonpolar solution was shown, and their luminescent characteristics were studied. Bound excited states for three possible exciplex structures and their corresponding emission spectra were calculated, and the optimal exciplex structure was shown to agree with experiment.
