  • Patent number: 8883321
    Abstract: Compositions of a mixture of a thiol material and a material that contains a reactive unsaturated carbon-carbon bond that can be polymerized 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 polymerizing a thiol material and an ene material. The process for forming such an OLED, including the deposition of a layer of material comprising the polymerizable 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.

  • Patent number: 7736534
    Abstract: Compositions of a mixture of (A) a polymerizable compound, which undergoes polymerization 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 polymerization 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 polymerizing such a composition. A method for forming an OLED, including depositing a layer containing the polymerizable composition from solution and exposing the layer to heat or actinic radiation to induce polymerization, is also disclosed.
