摘要:
The present invention relates to novel polymers which comprise spirobifluorene and fluorine units of the formulae (I) and (II) and may further comprise additional structural elements which may have charge transport properties, hole transport properties and/or electron transport properties.Such materials display a significantly improved property profile in electronic components, particularly when used in a PLED, in particular as electroluminescence material, in organic integrated circuits (O-ICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic solar cells (O-SCs) or organic laser diodes (O lasers).

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.
摘要:
The invention relates to novel compounds containing 2,1,3-benzothiadiazole. Said compounds can be used as active components (=functional materials) in a series of different applications that can be attributed in the broadest sense to the electronics industry. The inventive compounds are defined by the formulae (I), (II), (III), (IV), (V), (VI), (VI), (VIII), (IX), (X) and (XI).

摘要:
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.
