Photo- and Electroluminescence of Substituted Divinyl Dibenzothiophene Sulfone

The spectral properties of two substituted divinyl dibenzothiophene sulfone in solutions of tetrahydrofuran, polyvinylcarbazole films, and films obtained by thermal vacuum deposition are investigated. The ability of these compounds in thin-layer ITO/PEDOT:PSS/NPD/L/ Ca/Al and ITO/PEDOT:PSS/PVK+L/ Ca...

Summary:The spectral properties of two substituted divinyl dibenzothiophene sulfone in solutions of tetrahydrofuran, polyvinylcarbazole films, and films obtained by thermal vacuum deposition are investigated. The ability of these compounds in thin-layer ITO/PEDOT:PSS/NPD/L/ Ca/Al and ITO/PEDOT:PSS/PVK+L/ Ca/Al structures (L denotes the examined luminophore) to emit radiation at applied voltage is investigated. It is shown that the spectra of photo- and electroluminescence in the film have a strong red shift of ~100 nm compared to the photoluminescence in solutions. It is suggested that radiation belongs to excimers.
