The invention relates to the use of an organic mesomeric compound as organic dopant for doping an organic semiconducting matrix material for varying the electrical properties thereof. In order to be able to handle organic semiconductors more easily in the production process and to be able to produce electronic components with doped organic semiconductors more reproducibly, it is proposed that as mesomeric compound a quinone or quinone derivative or a 1,3,2-dioxaborine or a 1,3,2-dioxaborine derivative may be used, which under like evaporation conditions has a lower volatility than tetrafluorotetracyanoquinonedimethane (F4TCNQ).

La présente invention a pour objet l'utilisation d'un composé organique mésomère comme dopant pour une matrice semi-conductrice organique pour en faire varier les propriétés électriques. Pour être en mesure de manipuler plus facilement des semi-conducteurs organiques lors du procédé de production et pour être en mesure de produire des composants électroniques à semi-conducteurs organiques dopés de façon plus reproductible, il est proposé d'utiliser comme composé mésomère une quinone ou un dérivé de quinine, la 1,3,2-dioxaborine ou un dérivé de celle-ci, qui dans des conditions semblables d'évaporation a une volatilité inférieure à celle du 2,3,5,6-tétrafluorocyclohex-2,5-diène-1,4-diylidènebis(propanedinitrile) (F4TCNQ).
