摘要:
The present invention relates to white-emitting copolymers which are obtained by a combination of blue-, green- and red-emitting repeating units. The copolymers of the invention display better film formation and an improved efficiency when used in polymeric organic light-emitting diodes compared to materials according to the prior art.
