Abstract: An organic light emitting diode (OLED) having an improved service life and improved transport of negative charge carriers. The organic light emitting diode based on an organic semiconductor material in which the transport of negative charge carriers and the stability with respect to reduction are determined by azahetarylene/Lewis acid complex units.

Abstract: A polymer mixture emits a broad spectrum of visible light that appears white or near-white in the aggregate. The polymer mixture comprises two (or more) components in the active layer. A heavy atom, such as platinum and/or iridium, present in the backbone of the mixture acts via a spin-orbit coupling mechanism to cause the ratio of fluorescent to phosphorescent light emission bands to be of approximately equal strength. These two broad emissions overlap, resulting in an emission spectrum that appears to the eye to be white.
