Abstract:
The present invention relates to conjugated polymers which comprise both structural units of the formula (1) and also structural units of the formula (2). The materials according to the invention are more readily soluble, display improved air stability and display a smaller voltage increase during prolonged operation when used in a polymeric organic light-emitting diode (PLED) than polymers according to the prior art.
