Light-emitting composition and devices including the same, the composition including a fluorescent light-emitting material and a polymer having a conjugating repeat unit and a non-conjugating repeat unit in a backbone of the polymer, and in which the conjugating repeat unit provides at least one conjugation path between repeat units linked to it; the non-conjugating repeat unit reduces conjugation of the polymer as compared to a polymer in which the non-conjugating repeat unit is absent; and a triplet excited state energy level of the light-emitting material is higher than a triplet excited state energy level of the non-conjugating repeat unit.

Polymer and organic light-emitting device

A method of forming a polymer comprising a conjugated backbone and side-groups pendant from the conjugated backbone wherein the method comprises the steps of: polymerizing one or more monomers to form a precursor polymer comprising the conjugated backbone and precursor groups pendant from the conjugated backbone, and subsequently converting the precursor groups to the side-groups.

Method of forming a polymer comprising a conjugated backbone

A white light emitting material comprising a polymer having an emitting polymer chain and at least one emitting end capping group.

White light emitting material

Monomer, polymerization method, and polymer

A method for forming a polymer comprising the polymerization of a plurality of monomers, wherein at least one of the plurality of monomers is one or both of: a charge transporting unit and a hydrocarbon monomer in which at least one carbon atom has been substituted by an atom or group with a greater quantity of unshared valence electrons than the carbon atom it has been substituted for, and wherein at least one of the plurality of monomers comprises an end-capping compound at one end of said monomer, the end-capping compound preventing polymerization at the end, wherein the end-capping compound is not charge transporting and comprises at least two rings. The end capping compound preferably consists of or includes a structural unit having the formula: (Ar)&#x2014;X, wherein Ar in each occurrence independently represents an aryl or heteroaryl group; X represents a leaving group comprising a boron derivative group or halogen; and n is 2 or more.

Polymer and polymerization method

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.

Electroluminescent materials and optical device

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 free-flowing compositions in a pouch having one or more compartments. The compartment and preferably the pouch as a whole are made from stretchable material, typically an elastic film which is water-soluble. The compositions are preferably cleaning compositions or fabric care compositions, in particular laundry or dish washing compositions.

Water-soluble stretchable pouches containing compositions

A monomer having general Formula (I) which may be substituted or unsubstituted: where E and E are the same or different and are reactive groups capable of undergoing chain extension; X is O, S, NR, RC&#x2014;CRor R&#x2550;CR; Y is O, S, NR, RC&#x2014;CRor RC&#x2550;CR; R, RRand Rare the same or different and each is independently H or a substituent group; and each Ar is the same or different and is independently a substituted or unsubstituted aryl or heteroaryl group. 

Monomer for use in preparation of a polymer to be used in optical devices

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

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 multi-compartment pouch made from a water-soluble film and having at least two compartments, where the multi-compartment pouch comprises a composition comprising a solid component and a liquid component, wherein at least one compartment comprises a solid component and at least one compartment comprises a liquid component.

Pouched compositions

A multi-compartment pouch made from a water-soluble film and having at least two compartments, where the multi-compartment pouch comprises a composition comprising a solid component and a liquid component, wherein one compartment comprises the solid component and another compartment comprises the liquid component.
