Transition metal complexes with carbene ligands as emitters for organic light-emitting diodes (OLEDs)

The present invention relates to light emitting compounds, especially to triplett emitters suitable for electrooptical applications. Compounds according to the invention are organometallic complexes of a metal, preferably Ir, having a backbone of one five-membered ring that is linked to a five- or six-membered ring, by an intermediate six-membered ring. These compounds are suitable for adaptation to the emission of light in the UV to NIR range by adaptation of atoms or groups within at least one of the five-membered or six-membered ring structures.

Triplet emitter having condensed five-membered rings

A two-layered anode (') has a lower layer () including a non-conductive carrier material to which a conductive electrode layer (&#x2032;) is applied. Non-conductive areas, formed by partial removal of the electrode layer, have a predetermined structure corresponding to the structure of a structured polymer film () to be formed. The anode (&#x2032;) is connected with a platinum cathode in an electrolyte into which compounds of low molecular weight, preferably monomers of the polymer film (), are introduced. During current flow, a conductive polymer film () of the predetermined structure is formed on conductive areas brought into contact with the electrolyte. A non-conductive substrate layer () is applied to the structured polymer film (). The structured polymer film () adheres to the non-conductive substrate layer () and can be released from the electrode (&#x2032;) without damaging the electrode.
