- the term OLEDs are understood to mean electronic devices which have one or more layers containing organic compounds and which emit light when an electrical voltage is applied.
- the structure and the general functional principle of OLEDs are known to the person skilled in the art. In the case of electronic devices, in particular OLEDs, there is great interest in improving the performance data. A completely satisfactory solution has not yet been found on these points.
- Emission layers and layers with a hole-transporting function have a major influence on the performance data of electronic devices.
- New compounds are still being sought for use in these layers, in particular hole-transporting compounds and compounds which can serve as hole-transporting matrix material, in particular for phosphorescent emitters, in an emitting layer.
- compounds are sought in particular that have a high glass transition temperature, high stability, and high conductivity for holes.
- a high stability of the connection is one Prerequisite for achieving a long service life for the electronic device.
- triarylamine compounds such as spirobifluorenamines and fluorenamines are known as hole transport materials and hole transporting matrix materials for electronic devices.
- a group A is bound to a unit R, this means that no group R 1 or R 2 is bound to the relevant position, so that this position is free for binding to group A.
- an aryl group is understood to mean either a single aromatic cycle, that is to say benzene, or a condensed aromatic polycycle, for example naphthalene, phenanthrene or anthracene.
- a condensed aromatic polycycle consists of two or more individual aromatic rings condensed with one another. Condensation between cycles is to be understood as meaning that the cycles share at least one edge with one another.
- an aryl group contains 6 to 40 aromatic ring atoms. Furthermore, an aryl group does not contain a hetero atom as an aromatic ring atom, but only carbon atoms.
- a heteroaryl group is understood to mean either a single heteroaromatic cycle, for example pyridine, pyrimidine or thiophene, or a condensed heteroaromatic polycycle, for example quinoline or carbazole.

- an aromatic ring system is a system which does not necessarily contain only aryl groups, but which can additionally contain one or more non-aromatic rings which are condensed with at least one aryl group. These non-aromatic rings only contain carbon atoms as ring atoms. Examples of groups encompassed by this definition are tetrahydronaphthalene, fluorene and spirobifluorene.
- aromatic ring system also includes systems which consist of two or more aromatic ring systems which are linked to one another via single bonds, for example biphenyl, terphenyl, 7-phenyl-2-fluorenyl, quaterphenyl and 3,5-diphenyl-1-phenyl.
- an aromatic ring system contains 6 to 40 carbon atoms and no heteroatoms in the ring system.
