  • the object of the present invention is therefore to provide a new electrode with improved (opto) electronic properties for organic semiconductor components and optoelectronic components.
  • the invention relates to an electrode for optoelectronic and / or organic semiconductor components, which comprises allotropes.
  • the invention also combines, for example, allotropes with organic conductors or semiconductors (typically conjugated polymers) to form a semi-transparent or non-transparent electrode.
  • the electrodes can comprise the allotropes either in their metallic conductive form or in their semiconducting form.
  • metallic-conductive allotropes are, for example, from the literature (ZF Ren, ZP Huang, J.. Xu, DZ Wang, JH Wang, L. Calvet, J. Chen, JF Klemic, and MA Reed, "Large Arrays of Well-Aligned Carbon Nanotubes ", Proceedings of 13th International Winter School on Electronic Properties of Nove Materials, Pages 263-267, (1999).
  • Nanotubes have a variety of unique electronic, optical and mechanical properties.
  • Single-walled nanotubes have high tensile strength and, depending on the diameter and chirality, can be metallic, semiconducting or insulating.
  • chemical derivatization of nanotubes can also make sense, because this can influence their solubility and processability.
  • the derivatized and / or soluble nanotubes can be used as part of a phase mixture in organic functional polymers of microelectronics.
  • Spherical allotropes such as nanotubes are e.g. in Nature 1991, vol. 354, pages 56 to 58. There are silicon and carbon nanotubes.

  • a combination of at least two elements selected from the group of conductive substrates (conductive oxides (ITO), doped semiconductors (silicon, germanium ...), - of metals such as AL, Ag ... is also suitable for positive / negative electrodes. . or
  • non-conductive substrates glass, foils, ...) on which allotropes are applied either in their purest form or in mixtures with conductive or non-conductive binding materials (polymers ).
  • organic material or “functional polymer” or “polymer” here encompasses all types of organic, organometallic and / or organo-inorganic plastics (hybrids), in particular those which are described in English e.g. be called “plastics”. These are all types of substances with the exception of the semiconductors that form the classic diodes (germanium, silicon) and the typical metallic conductors. A restriction in the dogmatic sense to organic material as carbon-containing material is therefore not provided, but rather is also due to the widespread use of e.g. Silicones thought.
  • polymer in the functional polymer is historical and therefore contains no information about the presence of an actually polymeric compound.
  • functional polymer can refer to semiconducting, conducting and / or insulating substances.
  • Metallic allotropes or nanotubes grown (formed) on a substrate result in conductive electrodes with a a three-dimensional structure, for example a two-dimensional array with nanotubes on it, which has a large surface area.
  • the increase in surface area that is to say the ratio of the substrate surface on which the allotorop is applied, to the usable electrode surface, that is to say the active area, can be increased further by the density of the planting, that is to say the grown allotropes and / or by their length ,
  • Composite material for electrodes can e.g. can be produced by embedding metallic allotropes in a matrix of conductive functional polymer. In this mixture of the allotrope with the organic functional polymer, the conductivity and / or the transparency of the electrode can be optimized via the amount of allotrope, its concentration in the matrix. From this composite material e.g. an electrode can be printed as a solution.
  • semiconducting allotopes can also be used as the positive electrode (electron acceptor) for heterojunction applications. It has recently been shown that nanotube composites with conjugated polymers show a strong photo effect (SB Lee, T. Karayama, H. Kajii, H. Araki and K. Yoshino, Synth. Met 121 (2001) 1591-1592 ).
