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.

摘要:
The present invention relates to solutions of at least one organic semiconductor in at least one organic solvent with at least one aliphatic or cycloaliphatic alkene, and to the use thereof for the production of layers of organic semiconductors on substrates, in particular for the electronics industry.
摘要:
The present invention relates to polymers which contain certain triarylamine units of the Formula (1) The materials according to the invention exhibit a longer lifetime than materials in accordance with the prior art and therefore more suitable for use in polymeric organic light-emitting diodes.
摘要:
The present invention relates to conjugated polymers comprising specific carbazole structural units. The materials according to the invention display steeper current-voltage curves and are therefore better suited to use in organic light-emitting diodes than are comparative polymers which do not contain these units.
