  • Patent number: 9375392
    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.

  • Patent number: 9276223
    Abstract: The invention relates to novel metal-organic materials for hole injection layers in organic electronic components. For example, in light-emitting components such as organic light diodes (OLED) or organic light-emitting electrochemical cells (OLEEC) or organic field effect transistors or organic solar cells or organic photo detectors. Luminescence (cd/m2), efficiency (cd/A), and service life (h) of organic electronic components such as from organic light diodes in particular are highly dependent on the exciton thickness in the light-emitting layer and on the quality of the charge carrier injection and are also limited by same, among other things. The invention relates to a hole injection layer consisting of quadratic planar mononuclear transition metal complexes such as copper 2+ complexes, for example, which are embedded into a hole-conducting matrix.

  • Patent number: 9169434
    Abstract: This invention presents, firstly, the principle that simple and known emitter materials which are uncharged per se, as known, for example, from OLED technology, can be converted to a charged species by the introduction of a charged imidazolinium radical. This charged species can then be used in organic light-emitting electrochemical cells.
