Abstract: | The characteristics of intra- and intermolecular electronic processes in crystalline dibenzotetraazaannulene were established based on an analysis of the electronic absorption spectra of thin films. It was shown that the specific spectral characteristics of this substance are due to its stack structure in the solid state.L V.
