    • The invention relates to an organic light-emitting diode (OLED) having an improved lifetime and improved transport of negative charge carriers. The organic light-emitting diode is based on an organic semiconductor material, in which the transport of negative charge carriers and stability with respect to reduction is achieved with triarylated Lewis acid units, in particular perarylated borane units. This leads to an improved lifetime of the emission layer which in turn increases the lifetime of the component and eliminates the need for correcting brightness during operation. Furthermore, the invention relates to organic light-emitting diodes in which the position of the emission zone in the emitter layer and the color of the emission can be influenced in a targeted manner through triarylated Lewis acids such as perarylated borane units.
    • 本发明涉及一种有机发光二极管(OLED),其具有改善的寿命并改善了负电荷载流子的传输。 有机发光二极管基于有机半导体材料,其中负电荷载流子的转运和相对于还原的稳定性通过三芳基化路易斯酸单元,特别是芳芳基化硼烷单元实现。 这导致发光层的寿命改善,这又增加了元件的寿命,并且消除了在操作期间校正亮度的需要。 此外,本发明涉及有机发光二极管,其中发射层中的发射区的位置和发射的颜色可以通过三芳基化的路易斯酸例如过芳基化的硼烷单元以目标方式受到影响。
