ABSTRACT

Conjugated polymers containing ansa substructures and their use as electroluminescence materials.Conjugated polymers containing ansa substructures, which contain aromatic groups and in which adjacent aromatic groups are connected to one another in such a way that one ring atom of one aromatic group is directly linked to one ring atom of the other aromatic group and any further linkages of these two aromatic groups are possible only via a bridge containing at least one tetravalent carbon atom and/or heteroatom.The polymers of the invention having ansa substructures are outstandingly suitable as electroluminescence materials, since they have a very high color purity.

Conjugated polymers containing ansa substructures and their use as electroluminescence materials.

Conjugated polymers containing ansa substructures, which contain aromatic groups and in which adjacent aromatic groups are connected to one another in such a way that one ring atom of one aromatic group is directly linked to one ring atom of the other aromatic group and any further linkages of these two aromatic groups are possible only via a bridge containing at least one tetravalent carbon atom and/or heteroatom.

The polymers of the invention having ansa substructures are outstandingly suitable as electroluminescence materials, since they have a very high color purity.
