OLEDs doped with phosphorescent compounds

摘要

Organic light emitting devices are disclosed, which comprise a heterostructure for producing electroluminescence, wherein the heterostructure comprises an emissive layer containing a phosphorescent dopant compound. For example, the phosphorescent dopant compound may comprise platinum octaethylporphine (PtOEP), which is a compound having the chemical structure with the formula:
