Beschreibung
Zusammenfassung:The invention relates to the use of the new poly(p-phenylenevinylene) derivative, poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene-1,2-ethenylene-2,5-dimethoxy-1,4-phenylene-1,2-ethenylene] (M3EH-PPV) as electroluminescent material. The invention is also directed to organic light-emitting diodes (OLEDs) based on the above material, which diodes are remarkable for a significantly increased operating temperature range, as well as to a process for manufacturing said OLEDs by applying said M3EH-PPV directly from a solution in the form of a film onto the substrate or the coated substrate.
