DFT calculations and comparison with the corresponding isocyanurates evidence the impact of the oxygen-for-sulfur replacement on the electronic structure and linear optical properties of these heterocycles. A bathochromic shift of the absorption bands and more efficient quenching of the fluorescence was observed.This project was supported by ANR (ANR-17-CE07-0033-01 project).application/pdfen-AU© 2020 by the authors.
