Patent number: 9570686Abstract: 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. This leads to an improved service life of the emission layer, which firstly increases the service life of the component and avoids readjustment of the brightness during operation. Organic light emitting diodes are disclosed in which the position of the emission zone in the emitter layer and the color of the emission can be specifically influenced by azahetarylene/Lewis acid complex units.Type: GrantFiled: July 26, 2005Date of Patent: February 14, 2017Assignee: OSRAM OLED GmbHInventors: Karsten Heuser, Arvid Hunze, Andreas Kanitz

Patent number: 8580392Abstract: 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.Type: GrantFiled: March 23, 2005Date of Patent: November 12, 2013Assignee: Osram Opto Semiconductors GmbHInventors: Karsten Heuser, Arvid Hunze, Andreas Kanitz, Wolfgang Rogler, Debora Henseler
