NOVELTY - As organic doping agent for the doping of an organic semiconductive matrix material, as blocker layer, as charge injection layer or as organic semiconductor itself, an organic mesomeric compound, which is an oxocarbon, pseudooxocarbon or radialene compound, is used.    USE - As organic doping agent for the doping of an organic semiconductive matrix material, as blocker layer, charge injection layer, organic semiconductor, organic conductor or as organic ferromagnets and in electronic components in the form of an organic light-emitting diode, photovoltaic cell, organic solar cell, organic diode or an organic field effect transistor (claimed).    ADVANTAGE - The compounds overcome the disadvantages of prior, i.e they can be used as doping agent for doping organic semiconductors, can be more readily handled in the production process and result in electronic components whose organic semiconductive materials can be reproducibly manufactured. The compounds are extremely diffusion-stable in organic layers and the production processes can be better controlled and can be carried out with lesser expense in a more reproducible manner by higher evaporation temperature and lower volatility. The doped semiconductive materials and resulting electronic components have improved long-time stability of electro-optical properties such as light yield.
