Compositions of a mixture of a thiol material and a material that contains a reactive unsaturated carbon-carbon bond that can be polymerised to form a charge-transporting or luminescent film are described, as is an organic light-emitting diode (OLED) device comprising at least one such charge-transporting or emissive layer that has been formed by polymerising a thiol material and an ene material. The process for forming such an OLED, including the deposition of a layer of material comprising the polymerisable composition, from solution, exposing said layer to actinic radiation through a mask, and then optionally developing said film to form a photopatterned film, is also disclosed.
A method of forming an electroluminescent device comprising the steps of: providing a substrate comprising a first electrode for injecting charge carriers of a first type; forming an electroluminescent layer having a surface by depositing onto the substrate a composition comprising a host material and a light-emitting dopant monomer of formula (I):
A-C—(X)
n
(I)
wherein X represents a polymerisable group; A represents a light-emitting group; C represents a bond or a spacer group and n is an integer; rendering at least some of the electroluminescent layer insoluble in a solvent by polymerising the monomer of formula (I); exposing the electroluminescent layer to the solvent; and depositing a second electrode capable of injecting charge carriers of a second type over the electroluminescent layer.

Compositions of a mixture of (A) a polymerisable compound, which undergoes polymerisation on exposure to heat or to actinic radiation, having the general formula
wherein Q is an organic charge transporting fragment, L is a linker group, X is a group capable of undergoing free radical or anionic polymerisation on exposure to heat or actinic radiation, m is 0 or 1, and n is an integer having a value of 2 or more; and (B) a phosphorescent material are described, as is an organic light-emitting diode (OLED) device comprising at least one emissive layer that has been formed by polymerising such a composition. A method for forming an OLED, including depositing a layer containing the polymerisable composition from solution and exposing the layer to heat or actinic radiation to induce polymerisation, is also disclosed.
