Spectral behaviors of the luminescence of phenoxazine and its fluorosubstituted analog are compared using the methods of quantum chemistry and electron spectroscopy. Fluorination causes a displacement of the absorption bands towards longer wavelengths. The fluorine atoms were shown to be inactive directly in the process of a charge transfer in a molecule, giving rise only to the electron-acceptor induction effect on the intermolecular processes. This results in changing the molecular geometry and its acid-based properties.
