A polymer containing an optionally substituted repeat unit of formula (I) wherein each R is the same or different and represents H or an electron withdrawing group, and each Ris the same or different and represents a substituent. 

Polymers, their preparation and uses

An organic light emitting device having a phase-separated light-emissive layer comprising:

Phosphorescent OLED

A conductive polymer composition comprising a conductive polymer in a solid polyelectrolyte.

Conductive polymer compositions in opto-electrical devices

A polymer comprising a first repeat unit comprising ArXwherein ArXcomprises a substituted or unsubstituted heteroaryl group and each X is the same or different and independently comprises a substituted or unsubstituted aryl or heteroaryl group and a second repeat unit that is adjacent to the first repeat unit wherein each X that is part of a main body of the polymer backbone is directly conjugated to the second repeat unit.

Polymer, its preparation and uses

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

A semiconductive hole transport material containing polar substituent groups, the polar substituent groups substantially not affecting the electronic properties of the hole transport material and the hole transport material being soluble in a polar solvent.

Polar semiconductor hole transporting material

A process for the preparation of a polymerizable unit for production of a hole transporting polymer for use in an optical device, which process comprises reacting in the presence of S to form  wherein each R is the same or different and is independently H or a substituent group; n is O or an integer from 1 to 100; Ar and Ar' are the same or different and are each aromatic or heteroaromatic groups which are substituted or unsubstituted; Y is a direct bond, a light emissive moiety, a hole transporting moiety or an electron transporting moiety; and X is a polymerizable group.

Optical devices and their manufacture

A polymer for use in an opto-electrical device comprising aromatically conjugated repeat units of optionally substituted 9,9-dimethylfluorene.

Opto-electrical polymers and devices

A luminescent polymer comprising a triarylene repeat unit which comprises a triarylene of general formula (I) which is substituted or unsubstituted and an arylene repeat unit -[-Ar-]- that is different from the triarylene repeat unit wherein X, Y, and Z are each independently O, S, CR, SiRor NR and each R is independently alkyl, aryl or H.

Luminescent polymer

An opto-electrical device comprising: a first electrode for injecting charge carriers of a first polarity; a second electrode for injecting charge carriers of a second polarity; and a layer of organic material disposed between the first and second electrodes, the layer of organic material comprising a blend of a first charge transporting and/or light-emissive polymer and a second charge transporting and/or light-emissive polymer, wherein at least the first polymer is cross-linked providing a first cross-linked matrix in which the second polymer is disposed.

Opto-electrical devices and methods of making the same

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

A method of manufacturing an electroluminescent device which has an anode and a cathode and arranged between the anode and the cathode a light emissive layer, also includes an anode protection layer which protects the anode against the effects of converting a precursor polymer to a semiconductive conjugated polymer which constitutes the light emissive layer. This has been found to increase the brightness and half-life of devices.
