Abstract
The invention relates to a use of the guanidinium cation and to a light-emitting component. This invention for the first time describes matrix materials and emitters for uses in organic electrochemical light-emitting cells containing a guanidinium cation unit. Guanidinium groups as a cationic system promise a wide electrochemical window and hence stable components. The route to guanidinium systems is described in detail in the literature.
