    Abstract: 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.

    Abstract: The organic electronic component (100) comprises a transparent first electrode (1), an organic layer sequence (3) having first and second charge carrier transport layers and an active region, and a transparent second electrode (2). The first charge carrier transport layer is disposed between the active region and the first electrode, and the second charge carrier transport layer is disposed between the active region and the second electrode. The charge carrier transport layers comprise a matrix material with a dopant. The matrix material and the dopant form charge-transfer-complexes. The organic electronic component (100) comprises a transparent first electrode (1), an organic layer sequence (3) having first and second charge carrier transport layers and an active region, and a transparent second electrode (2). The first charge carrier transport layer is disposed between the active region and the first electrode, and the second charge carrier transport layer is disposed between the active region and the second electrode. The charge carrier transport layers comprise a matrix material with a dopant. The matrix material and the dopant form charge-transfer-complexes, which absorb a part of an electromagnetic radiation falling from outside on the organic radiation-emitting component with first and second absorption spectra. The first charge carrier transport layer causes a predetermined color impression of the component in a switched-in electronic operating condition and the second charge carrier transport layer causes a predetermined color impression of the component in a switched-off electronic operating condition, where the predetermined color impression is noticeable through the electrodes by the external observer. The first charge carrier transport layer comprises a first layer stack with first and second layers, which have the matrix material and the dopant and are differentiated from each other, and is a hole-transport layer and an electron-transport layer. The dopant comprises metal oxide with group of metals, metal organic compound and/or organic material, aromatic organic material having substituents, and alkali metal salt, earth alkali metal salt and/or metal organic compounds. The metal organic compound comprises a metal complex with hydropyrimidopyrimidine, and group of metals. The dopant has a concentration of 5% in the matrix material. The active region is suited to radiate the electromagnetic radiation with an emission spectrum in the switched-in operating condition. The emission spectrum and the first absorption spectrum are partially same. The first charge carrier transport layer has a saturable absorption coefficient. The color impression noticeable in the switched-off operating condition is not noticeable in the switched-in operating condition by the first charge carrier transport layer.
