Abstract: Electrochemically active formulations may be used for flashing electrochromic displays, in particular for those that in addition to blinking can switch on a permanent symbol with the blinking display. The formulations contain at least two chemically different dye systems. The formulations provide a first dye system that is reversibly switchable at a low voltage, hence suitable for blinking representation of symbols. A second dye system is activated at a higher voltage and is suitable for permanent display of symbols due to the bistability or irreversibility thereof.

Abstract: 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.
