Abstract

The present application relates to an electronic device comprising a xanthene or thioxanthene compound of a particular formula. The electronic device is preferably an organic electroluminescent device (OLED). The application further relates to particular xanthene or thioxanthene compounds as such, and to the use thereof in the abovementioned devices, and to processes for preparation thereof.

Claims (4)

1 . An organic electroluminescent device which comprises a compound selected from the group consisting of compounds of Formulae (S-1) through (S-13) and optionally a p-dopant,

in an electron blocking layer and

wherein if the p-dopant is present, the p-dopant is selected from the group consisting of quinodimethane compounds, azaindenofluorenediones, azaphenalenes, azatriphenylenes, I2, transition metal oxides, and compounds of formulae (D-1) to (D-13)

wherein the organic electroluminescent device comprises a layer adjacent to the anode, which comprises a p-dopant selected from the group consisting of quinodimethane compounds, azaindenofluorenediones, azaphenalenes, azatriphenylenes, I2, transition metal complexes, and the compounds of formulae (D-1) to (D-13).
