A composition adapted for use in the manufacture of an organic light-emissive device by passing the composition through one or more openings under pressure to deposit the composition, the composition comprising: a semi-conductive organic host material; a luminescent metal complex; and a first solvent, wherein the first solvent has a structure: 

Compositions and methods for manufacturing light-emissive devices

A print head module () for depositing a substance has an axis and a plurality of print heads () provided with nozzles (). The heads are distributed along the axis to form an elongate compound head having nozzle redundancy by arranging the heads in partially overlapping relation to one another. This allows deposition of the substance from the nozzles in uniform swathes having different angles transverse to the axis.

Print head module

The invention relates to organic semiconductive polymers comprising a new backbone system, monomers for the preparation of such polymers, methods for the preparation of such polymers and the use of such polymers in organic optoelectronic devices.

Aryl-substituted polyindenofluorenes for use in organic electroluminiscent devices

An improved composition for ink jet printing an opto-electrical device, which composition comprises a solution-processable host material and a metal complex, wherein the viscosity of the composition exceeds 12 mPa&#xb7;s at 20&#xb0; C.

Opto-electrical devices and methods of manufacturing the same

A composition suitable for fabricating an electronic device such as an OLED using an ink-jet printing technique comprises a conducting or semi-conducting organic material and a solvent, the solvent having a boiling point of greater than 250&#xb0; C. and a viscosity of less than 5 cPs. The composition preferably has a viscosity in the range between 0.1 and 20 cPs, and the solvent preferably has the formula: 

Solvent for a printing composition

A composition for use in the manufacture of an opto-electrical device, the composition comprising: a conductive or semi-conductive organic material; a solvent; and a first additive, wherein the first additive is an alcohol ether having a boiling point lower than 170&#xb0; C.

An optionally substituted oligomer or polymer comprising a repeat unit of formula (I); wherein each Arand Aris the same or different and independently represents an optionally substituted aryl or heteroaryl; n is at least 1; Arrepresents an optionally substituted aryl or heteroaryl comprising a linking ring to which the two nitrogen atoms are both directly linked; and at least one of Arand either or both of Aris substituted with at least one substituent. 

Oligomers and polymers

An oligomer or polymer comprising a first repeat unit and a second repeat unit that may be the same or different, the first repeat unit having formula (I): wherein each E independently represents optionally substituted nitrogen or optionally substituted phosphorus, with the proviso that at least one E is optionally substituted phosphorus; each Ar, Arand Aris the same or different and independently represents an optionally substituted aryl or heteroaryl; n is 0-3; and in the case of unsubstituted nitrogen and phosphorus, the second repeat unit is directly conjugated to the first repeat unit. 

Oligomer and polymer comprising triphenyl phosphine units

The present invention relates to new semiconductive oligomers and polymers, a process for their manufacture and their use in thin film electronic and optical devices, such as organic light emitting diodes (OLED) and photovoltaic devices, eg. solar cells and photodetectors.

Polymer

The present invention relates to new semiconductive polymers, a process for their manufacture and their use in thin film electronic and optical devices, such as organic light emitting diodes (OLED) and photovoltaic devices, e.g. solar cells and photo detectors.

The instant invention relates to a new method for the synthesis of monomers and their use inter alia in the manufacture of semiconductive polymers. Monomers, in particular, asymmetric monomers, such as asymmetric fluorene compounds, are valuable material in the manufacture of semiconductive polymers. The know methods for producing asymmetric monomers, such as asymmetric fluorene compounds, are expensive due to the formation of by-products. The method according to the present invention avoids the formation of such by-products and is described in more detail in claimsto

Method for the production of monomers useful in the manufacture of semiconductive polymers

A process for preparing high molecular weight polymers or copolymers by Suzuki coupling. The catalyst used in the process comprises a source of palladium and a source of a phosphine characterized in that at least one substituent on the phosphine is an ortho substituted aryl group. The process is suitable for the preparation of polymers for use in electronic and optoelectronic applications.

Modified Suzuki-method for polymerization of aromatic monomers

A process for preparing a conjugated polymer, which comprises polymerizing in a reaction mixture (a) an aromatic monomer having at least two boron derivative functional groups selected from the group consisting of boronic acid groups, boronic ester groups, and borane groups, and an aromatic monomer having at least two reactive halide functional groups, or (b) an aromatic monomer having one reactive halide functional group and one boron derivative functional group selected from the group consisting of boronic acid groups, boronic ester groups, and borane groups, an amount of a catalyst suitable for catalyzing the polymerization of the aromatic monomers, and a base in an amount sufficient to convert the boron derivative functional groups into boron anionic groups, characterized in that the reaction mixture further comprises a first solvent and a second solvent with which said first solvent is substantially immiscible and an emulsifier in an amount sufficient to form an emulsion of the reaction mixture.
