Abstract: The present invention relates to OLED devices and stacks for OLED devices that include a symmetric emissive-layer architecture. In one embodiment, the present invention relates to an emissive stack having three layers, wherein the top and bottom layers emit light in the same or similar color region while the middle layer emits light in a different color region than the other two layers. In such an embodiment, the three layers are in contact with each other with no other layers in between. The symmetric emissive-layer architecture of the present invention can be used to improve the color stability of OLED devices.

Abstract: Methods of making novel organic compounds containing a twisted aryl group are provided. In particular, the compounds provided contain a 2-phenylpyridine ligand having a twisted aryl group on the pyridine portion of the ligand. The compounds may be used in organic light emitting devices, particularly as emitting dopants. Devices comprising the compounds containing twisted aryl may demonstrate improved color, efficiency, stability and manufacturing.

Abstract: A method for improving the operation of an OLED includes maximizing on-radiative transfer of excited state energy from the OLED's organic emissive material to surface plasmon polaritons in an enhancement layer by providing the enhancement layer no more than a threshold distance away from the organic emissive layer; and emitting light into free space from the enhancement layer by scattering the energy from the surface plasmon polaritons through an outcoupling layer that is provided proximate to the enhancement layer but opposite from the organic emissive layer.
