Display and lighting devices comprising phosphorescent excimers with preferred molecular orientation as monochromatic emitters
Abstract:
An organic light emitting diode having a substrate, a first electrode, a hole transporting layer proximate the first electrode, a second electrode, an electron transporting layer proximate the second electrode, and an emissive layer between the hole transporting layer and the electron transporting layer. The emissive layer includes a square planar tetradentate platinum or palladium complex, and excimers formed by two or more of the complexes are aligned such that emitting dipoles of the excimers are substantially parallel to a surface of the substrate.
