Abstract

The invention relates to chromophores exhibiting semiconductive properties, the production and use thereof as luminophores in organic light-emitting diodes (OLEDs) and organic solar cells. The invention more specifically relates to highly condensed boron complex compounds wherein the boron atoms have improved processability, solubility and the fluorescence quantum efficiency is increased by building up by spirocenters.
