Definitions

  • Hole transport layers hole blocking layers
  • -Electron transport layer- -electron injection layer-cathode materials for the hole injection layer and the optionally available further hole-transporting layers are preferably selected from indenofluorenamine derivatives, amine derivatives,
  • one or more layers of solution e.g. B. by spin coating, or with any printing process, such as. B. screen printing, flexographic printing, nozzle printing or offset printing, but particularly preferably LITI (Light Induced Thermal Imaging, thermal transfer printing) or ink-jet printing (inkjet printing) can be produced.
  • Soluble compounds are required for this. High solubility can be achieved by suitable substitution of the compounds.
