  • Organic solar cells O-SC
  • organic field-effect transistors O-FET
  • organic thin-film transistors O-TFT
  • organic switching elements O-IC
  • organic optical amplifiers or organic laser diodes O-lasers
  • OLEDs organic electroluminescent devices
  • Organic solar cells e.g. WO 98/48433, WO 94/05045), organic field-effect transistors (e.g. US 5705826, US 5596208, WO 00/42668), organic thin-film transistors, organic switching elements (e.g. WO 95/31833, WO 99/10939), organic optical amplifiers or organic laser diodes (e.g. WO 98/03566) have a similar general structure.
  • BESTATIGUNGSKOPIE The operating voltage is quite high, especially in the case of fluorescent OLEDs, and must therefore be reduced further in order to improve the power efficiency. This is particularly important for mobile applications.
  • the above-described problems of currently available OLEDs are largely caused by insufficient charge injection, charge transport and matrix materials.
  • the hole injection material (HTM) and hole transport material (HTM) are essentially CuPc (copper (II) phthalocyanine), PEDOT (poly (3,4-ethylenedioxy-2,5) -thiophene) or
  • PANI polyaniline
  • CuPc is generally applied to the anode as a hole injection layer by evaporation in a high vacuum. It has been shown in practice that it is difficult to reproduce sufficiently thin and homogeneous CuPc layers with such a process. Fluctuations in layer thickness mostly lead to short circuits and consequently to
  • CuPc has a very high evaporation temperature, typically above 400 ° C, so that the radiant heat occurring during evaporation deforms thermally sensitive positioning elements such as suspensions of shadow masks and shadow masks themselves, which can lead to imaging errors in the structuring process.
  • the polymeric hole injection materials PEDOT and PANI are applied to the anode from an aqueous solution by spin coating or printing processes (e.g. ink jet printing). PEDOT and PANI are strongly acidic polyelectrolytes that develop their (semi) conductive properties only through the action of a strong Brönsted acid on the organic polymer.

  • the OLEDs produced with these light-emitting inclusion compounds show very poor performance data compared to OLEDs which correspond to the prior art.
