Title:
CONJUGATED POLYMERS AND BLENDS CONTAINING CARBAZOLE, REPRESENTATION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO2004070772
Kind Code:
A3
Abstract:
The invention relates to conjugated polymers containing special carbazole structural units. The inventive materials have steep current-voltage curves and are therefore better for use in organic light-emitting diodes which can be used as reference polymers which do not contain said units.
