Abstract
The present invention relates to oxocarbon-, pseudooxocarbon- and radialene compounds as well as to their use as doping agent for doping an organic semiconductive matrix material, as blocker material, as charge injection layer, as electrode material as well as organic semiconductor, as well as electronic components and organic semiconductive materials using them.

Use of an organic mesomeric compound as organic doping agent for the doping of an organic semiconductive matrix material as charge injection layer, characterized in that the mesomeric compound is an oxocarbon-, pseudooxocarbon- or radialene compound with the following formula:
- in which n=1-4;
- each X1, X2, and X3 is independently selected from the group consisting of C(CN)2, (CF3)C(CN), (NO2)C(CN), C(halogen)2, C(CF3)2, NCN, O, S, NR1,
- wherein X4 and X5 are independently selected from the group consisting of C(CN)2, (CF3)C(CN), (NO2)C(CN), C(halogen)2, C(CF3)2, CN, O, S and NR1,
- in which Y=CN, NO2, COR1 or is perhalogenated alkyl;
- aryl or Ar is a substituted or unsubstituted aromatic hydrocarbon or biaryl, optionally polycyclic;
- hetaryl is a substituted or unsubstituted aromatic heterocyclic compound or biheteroaryl;
- and R1-R8 are independently selected from hydrogen, halogen, CN, NO2, COR1, alkyl, alkoxy, aryl and heteroaryl, wherein the molar doping ratio of dopant to matrix molecule, respectively the doping ratio of dopant to monomer unit of a polymeric matrix molecule, is from 1:1 to 1:100000.
Oxocarbon-, pseudooxocarbon- or radialene compound with the following formula
- in which n=1-4;
- in which for n=1:
- each X1-X3 is independently selected from (CF3)C(CN), C(CF3)2, as well as structures A-W4
- X4 and X5 are independently selected from (CF3)C(CN), C(CF3)2 and NCN;
- Y is selected from CN, COR1, perhalogenated alkyl groups;
- aryl or Ar is selected from substituted or unsubstituted aromatic hydrocarbon, also polycyclic, and biaryl, partially or completely hydrogenated or fluorinated;
- hetaryl and bihetaryl are selected from substituted or unsubstituted aromatic heterocyclic compound, also polynuclear, and also partially or completely hydrogenated or fluorinated heteroaromatics;
- R1-R8 are independently selected from hydrogen, halogen, CN, NO2, COR1, perhalogenated and/or partially halogenated alkyl groups, or substituted and/or unsubstituted aryl- and heteroaryl groups.
