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.
Claims9
An electronic component with an electronically functionally active region, wherein the electronically active region comprises a charge injection layer which consists of at least one oxocarbon, pseudo-oxocarbon, or radialene compound with the following formula:
- in which n=1-4;
- each X1, X2, and X3 is respectively 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 respectively 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, and NR1,
- wherein Y=CN, NO2, COR1 or is perhalogenated alkyl;
- aryl, respectively Ar is a substituted or unsubstituted aromatic hydrocarbon or biaryl, or optionally polycyclic;
- hetaryl is a substituted or unsubstituted aromatic heterocyclic compound or biheteroaryl, optionally polynucleic or partially or completely hydrated or fluorinated;
- and R1-R8 are independently selected from hydrogen, halogen, CN, NO2, COR1, alkyl, alkoxy, aryl, or heteroaryl.
