Title:
POLYMERS HAVING STRUCTURAL UNITS WITH ELECTRON TRANSPORT PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2012/016627
Kind Code:
A3
Abstract:
The present invention relates to a polymer which comprises at least one structural unit that has electron transport properties, to processes for preparing them and to mixtures (blends), solutions and formulations which comprise these polymers. The present invention further relates to the use of these polymers in electronic devices, more particularly in organic electroluminescent devices, known as OLEDs (OLED = Organic Light Emitting Diodes), and also to these organic electroluminescent devices themselves. The polymers of the invention exhibit improved efficiency, particularly when used in OLEDs.
