Abstract: Stoichiometry and stability of electron donor–acceptor complexes formed by dibenzothiophene and its alkylated derivatives with DDQ and TCNE in nonpolar organic solvents has been investigated. 4,6-Dimethyldibenzothiophene produces the most stable 1: 1 complex with DDQ in agreement with energy levels of the π-donors HOMOs and π-acceptors LUMOs calculated by DFT. The results make possible an employment of the complexes for multiplex determination of polycyclic aromatic pollutants using surface enhanced Raman spectroscopy.

Keywords: polycyclic aromatic sulfur heterocycles, dibenzothiophene, charge transfer complex, optical sensor, surface enhanced Raman spectroscopy, multiplex detection, silver nanoparticles.
