    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.
