Abstract

The present invention relates to use of an organic matrix material for producing an organic semiconductor material, characterized in that the organic matrix material is comprised at least partly of a spirobifluorene compound, and the glass transition temperature of the organic matrix material is at least 120° C. and the highest occupied molecular orbital (HOMO) of the matrix material is at a maximum energy level of 5.4 eV; and also to an organic semiconductor material and electronic component.
