A polymer dopant for electrially conducting, photoconducting and semiconducting components and devices and novel polymers comprising electron accepting groups that are suitable as polymer dopants.

Polymer dopants

Disclosed are formulations that contain an organic semiconducting compound, a hydrophobic surfactant containing a head group that is a chlorosilane, silazane or thiol group and a tail group that is an alkyl, fluoroalkyl or siloxane group, and a non-alcoholic organic solvent, and their uses in electrically conducting, photoconducting and semiconducting components and devices, for example, in integrated circuitry, organic field effect transistors, thin film transistors, organic photovoltaic devices, radio frequency identification tags and organic light emitting diodes.

Organic semiconductor formulation

The invention relates to new reactive mesogenic compounds with charge transport properties comprising at least two thiophene groups, their use as semiconductors or charge transport materials, in optical, electro-optical or electronic devices like for example liquid crystal displays, optical films, organic field effect transistors (FET or OFET) for thin film transistor liquid crystal displays and integrated circuit devices such as RFID tags, electroluminescent devices in flat panel displays, and in photovoltaic and sensor devices, and to a field effect transistor, light emitting device or ID tag comprising the reactive mesogenic charge transport compounds.

Reactive mesogenic charge transport compounds

The invention relates to formulations comprising one or more polymers with semiconducting, charge transport, photoconducting and/or photo- or electroluminescent properties and one or more organic solvents, to their use for the preparation of electrooptical or electronic devices, including field effect transistors (FETs), electroluminescent, photovoltaic and sensor devices, in particular by ink-jet printing, and to FETs and other semiconducting or light emitting components or devices comprising the formulations.

Formulation for ink-jet printing comprising semiconducting polymers

The invention relates to polymerizable charge transport compounds, their use as semiconductors or charge transport materials, in optical, electrooptical or electronic devices like for example organic field effect transistors (FET or OFET) for thin film transistor liquid crystal displays and integrated circuit devices such as RFID tags, electroluminescent devices in flat panel displays, and in plotovoltaic and sensor devices, and to a field effect transistor, light emitting device or ID tag comprising the polymerisable charge transport compounds.

Polymerizable charge transport compounds

The invention relates to new reactive mesogenic azulene derivatives, their use as semiconductors or charge transport materials, in optical, electro-optical or electronic devices like for example liquid crystal displays, optical films, organic field effect transistors (FET or OFET) for thin film transistor liquid crystal displays and integrated circuit devices such as RFID tags, electroluminescent devices in flat panel displays, and in photovoltaic and sensor devices, and to a field effect transistor, light emitting device or ID tag comprising the reactive mesogenic azulenes.

Reactive mesogenic azulenes

The invention relates to a prepolymer material based on monomeric, oligomeric or polymeric compounds with at least one ethylenically unsaturated (meth)acryloyl group. The problem of imperfect imprinting properties, escpecially of an unwanted adhering to the imprinting stamp or mold, is circumvented by a fluorinated organo silane surfactant as an additional component of the prepolymer material. Furthermore, the invention describes an imprinting process for the manufacture of polymer articles with relief on their surface. Better release properties of the polymer article from the stamp or mold are accomplished by applying a surfactant, comprising a fluorinated organo silane, onto the surface of the mold or stamp.
