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 present invention relates to organic electroluminescent devices which comprise a mixture of at least two materials in the electron-transport layer.
摘要:
The present invention relates to copolymers containing indenocarbazole derivatives having electron- and hole-transporting properties, in particular for use in the interlayer, emission layer and/or charge-transport layer of electroluminescent devices. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to electronic devices comprising these compounds.
摘要:
The present invention relates to electroluminescent polymers which comprise 2-vinylthiophenylbenzene derivatives as recurring units, to a process for the preparation thereof, to blends and formulations comprising these polymers, and to the use of these polymers in electronic devices, in particular in organic light-emitting diodes, so-called OLEDs.
摘要:
The present invention relates to novel formulations comprising an organic semiconductor (OSC) and one or more organic solvents. The formulation comprises a dimethyl anisole solvent. Furthermore, the present invention describes the use of these formulations as inks for the preparation of organic electronic (OE) devices, especially organic photovoltaic (OPV) cells and OLED devices, to methods for preparing OE devices using the novel formulations, and to OE devices, OLED devices and OPV cells prepared from such methods and formulations.
摘要:
The invention relates, inter alia, to an opto-electronic device having at least two electrodes (10, 15) and at least one light-emitting layer (EML) (12) arranged between the electrodes (10, 15), which comprises an electroluminescent organic material which emits light having a first wavelength spectrum, characterised in that at least one layer (1, 2, 5, 6) which comprises at least one colour converter is arranged between at least one of the at least one light-emitting layer (EML) and at least one electrode. The invention furthermore relates to a process for the production of an opto-electronic device of this type, and to the use of an opto-electronic device of this type as lamp or in a display.
摘要:
The present invention relates to systems for photoenergy up-conversion comprising polymers and sensitisers, where the triplet level of the polymer is lower than the triplet level of the sensitiser. These systems exhibit higher efficiency in up-conversion and are therefore more suitable for use in devices for up-conversion than polymers as used in accordance with the prior art.
摘要:
The present invention relates to phosphorescent copolymers comprising trifunctional triplet emitters. The polymers according to the invention are highly soluble, readily accessible synthetically and more suitable for use in organic light-emitting diodes than are comparative materials in accordance with the prior art.
摘要:
The invention relates to mixtures comprising at least one polymer, additionally comprising structural units containing at least one element from the 4th main group different from carbon and additionally comprising structural units that are triplet emissives. The inventive materials are better suited to the use in phosphorescent organic light emitting diodes than comparable prior art materials.
