  • PEDOT-PSS with various solvents, including glycol are known, for example from DE 197 57 542.
  • a disadvantage of these materials containing PEDOT-PSS is that the conductivity has been modified by adding solvent additives or other additives. This results in adverse effects on the printability of the polymer layers, with the conductivity still not being optimized.
  • a highly conductive functional polymer is required for organic solar cells, detectors or transistors as well as for organic light-emitting diodes on flexible substrates.
  • this polymer serves as an anode.
  • this PEDOT can be used as a material for the source-drain electrodes.
  • ITO indium tin oxide
  • flexible plastic substrates can be used.
  • the conductive properties of the polymer used for this should come very close to that of the ITO in order to achieve the same performance properties of the components.
  • ITO has a conductivity in the range of 10 4 S / cm and achieves a surface resistance of 20 Ohm / square with a layer thickness of 120 nm.
  • Commercially available PEDOT currently reaches 8 from Bayer or now HC Starck) up to 10 S / cm and from Agfa (Orgacon Folie) 120 S / cm.
  • the PEDOT / PSS dispersions used are currently water-based.
  • the object of the present invention is therefore to provide a material which has an optimized conductivity based on PEDOT-PSS.
  • the invention relates to a material for producing an organic functional layer based on PEDOT-PSS, in which the conductivity is optimized by replacing the solvent, that is to say substituting the first solvent with a second solvent.
  • water or another strongly polar solvent is used as the "first solvent" to be replaced.
  • the “first solvent *” is the solvent in which the functional polymer, PEDOT-PSS, is produced. Accordingly, the “second solvent” is the solvent that is ultimately present in the material in which the functional polymer shows the optimized conductivity.
  • a glycol-containing compound such as ethylene glycol or another alcohol is used as the second solvent, in particular also mixtures of several alcohols and / or alcohols with a carbon content of C4 to C10, branched and unbranched, including polyvalent ones Alcohols, or mixtures thereof, and mixtures with water, particularly preferably glycol and glycerol.

Accordingly, a restriction in the dogmatic sense to organic material as carbon-containing material is not intended, but rather is The term is not intended to be subject to any restriction with regard to the molecular size, in particular to polymeric and / or oligomeric materials, but the use of "small molecules” is also entirely possible. polymer "in the functional polymer is due to historical reasons and therefore contains no information about the previous are an actually polymeric compound and no statement as to whether it is a polymer mixture or a copolymer or not.
  • the main advantage of the conductive polymer (PEDOT) in ethylene glycol described here is that replacing the water with ethylene glycol significantly increases the conductivity. The reason for this increase has not yet been clarified. On the one hand it can lead to the formation of agglomerates during the replacement of the solvent, on the other hand the addition of ethylene glycol to the PEDOT / PSS chains can lead to improved electricity transport through the formation of hydrogen bonds.

  • PEDOT is used as an anode (replacement for ITO) in the field of OLEDs and solar cells on flexible Substrates used.
  • the anode can be applied in a structured manner using an existing printing process, the required conductivity being as close as possible to that of the ITO.

  • PEDOT In the area of organic transistors, highly conductive PEDOT is required in order to implement electrical leads or the source drain electrodes on a polymer basis. - In the field of organic solar cells or detectors, PEDOT is used as an electrode, supply line and as a recombination layer for tandem cells. - In the field of electronic components in general for diodes, resistors for IC + boards
  • Highly conductive PEDOT can also be used for both electrodes in a sandwich device (also for inverted construction).
