  • Organice electroluminescent materials and devices
    Patent number: 9397310
    Abstract: A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, a cathode and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material, that includes nanocrystals. The phosphorescent emissive dopant is bonded to the host material by a bridge moiety.
    Type: Grant

  • Aryloxyalkylcarboxylate solvent compositions for inkjet printing of organic layers
    Patent number: 9252363
    Abstract: A liquid composition (e.g., inkjet fluid) for forming an organic layer of an organic electronic device (e.g., an OLED). The liquid composition comprises a small molecule organic semiconductor material mixed in a solvent in which the solvent compound has the following formula: wherein R1 is C1-6 alkyl; R2 is C1-6 alkyl; and R3 is one or more optional substitutions independently selected from C1-6 alkyl and lower aryl.

  • HOST FOR ORGANIC LIGHT EMITTING DEVICES
    Publication number: 20140203259
    Abstract: A first device comprising a first organic light emitting device (OLED) is described. The first OLED includes an anode, a cathode, and an emissive layer disposed between the anode and the cathode. The emissive layer includes a phosphorescent emissive dopant and a host material. The host material includes inorganic nanocrystals where (i) at least 50% of ligands bonded to said nanocrystals are compact ligands, (ii) an average interparticle distance between adjacent nanoparticles is ?1 nm, or (iii) both. Also described are a method of making the emissive layer and a composition that includes the phosphorescent emissive dopant with the host materials that include the electronically-coupled inorganic nanocrystal host material.
