A method of forming an organic light emitting diode comprising the steps of: providing a substrate comprising a first electrode for injection of charge carriers of a first type; forming a charge transporting layer by depositing over the substrate a charge transporting material for transporting charge carriers of the first type, the charge transporting material being soluble in a solvent; treating the charge transporting layer to render it insoluble in the solvent; forming an electroluminescent layer by depositing onto the charge transporting layer a composition comprising the solvent, a phosphorescent material, and a host material; and depositing over the electroluminescent layer a second electrode for injection of charge carriers of a second type.

Optical device comprising a charge transport layer of insoluble organic material and method for the production thereof

A polymer comprising a first repeat unit of formula (I), wherein each Ar is independently selected from optionally substituted aryl or heteroaryl and the group of formula (I) is present in a molar ratio of less than or equal to 10%, and, optionally, a second, optionally substituted repeat unit having a single nitrogen atom in its backbone of formula &#x2014;Ar&#x2014;N(Ar)&#x2014;Ar&#x2014; in a molar ratio of no greater than 5%.

Polymers, their preparation and uses

A white light emitting device having an anode and a cathode and therebetween an organic electroluminescent layer which emits white light on the provision of a current between the anode and the cathode, said organic electroluminescent layer including a plurality of electroluminescent zones in laterally separated arrangement, the first of said electroluminescent zones including a first polymer and the second of said electroluminescent zones including a second polymer, wherein the first polymer includes a fluorescent blue light emitting species and the second polymer includes a fluorescent green light emitting species, said first and/or second zones further including a phosphorescent red light emitting species, such that together with the blue emitting species results in the emission of white light, said first and second polymers being physically incompatible so that separation of the zones pertains.
