Abstract

Nonradiative energy transfer of the electronic excitation energy of bifluorophor molecules modelling a repeating unit of an aromatic bifluorophor polymer chain was studied in solution. The study of the properties of luminescence spectra of azomethine-bifluorophor solutions and the methods of quantum-chemistry calculations showed that the description of this intramolecular nonradiative transfer of the electronic excitation energy according to the Förster mechanism requires taking into account the effect of molecular conformational isomerisation and conjugation effects.
