摘要:
The invention concerns non-conjugated luminophor compounds having semiconductor properties, as well as their production and their use in organic light-emitting diodes, organic solar cells, organic photodetectors and organic field effect transistors. Said luminophors are co-polyarylboranes of type K which are transformed, only when a suitable electric field is applied and/or when substituted by the aryl R substituent donor, into a type of structure which acts like a conjugated polymer. The symbols are as defined in Claim 1.
摘要:
A novel electroluminescent device is produced by printing an electroluminescent organic layer with a planographic printing process. Organic LEDs are formed in that the organic material is printed onto patterned electrodes on a substrate and the organic material is contacted by metallic electrodes formed following the printing process. Any of the accurate planographic printing processes is suitable, such as pad printing, offset printing, dry offset printing, letterpress printing, and intaglio printing. The resulting device may be a flat panel display with only a few discrete display fields or an intricate, pixeled multi-color or full-color electroluminescent display device or a light source.

摘要:
The invention relates to an organic light-emitting diode (OLED) featuring an increased service life and improved transport of negative charge carriers. Said organic light-emitting diode is based on an organic semiconducting material in which the transport of negative charge carriers and stability regarding reduction are determined by means of triarylated Lewis acid units, particularly perarylated borane units. This results in an improved service life of the emissive layer, which increases the service life of the component while dispensing with the need to readjust brightness during operation. The invention further relates to such organic light-emitting diodes in which the position of the emitter region in the emitter layer and the emission color can be influenced in a specific manner with the aid of triarylated Lewis acids such as perarylated borane units.
