Abstract: Organic light emitting devices (OLEDs) with emissive layers containing both phosphorescent Pt complexes and fluorescent emitters, are described. The devices presented employ both fluorescent and phosphorescent Pt complexes in order to redistribute the excited states to primarily reside on known stable fluorescent emitters to achieve high device operational stability but maintain the high efficiency characteristic of phosphorescent OLEDs.

Abstract: An organic light emitting diode (OLED) device includes an emissive layer having a first sublayer with a first emitter as a dopant, a second sublayer with a second emitter as a dopant, and a third sublayer with a third emitter as a dopant. The second sublayer is between the first sublayer and the third sublayer. A concentration of the first emitter in the first sublayer exceeds a concentration of the third emitter in the third sublayer, and the concentration of the third emitter in the third sublayer exceeds a concentration of the second emitter in the second sublayer.

Abstract: Porphyrins and porphyrin derivatives of General Formulas I-V are suitable for use as donor-type materials for photovoltaic cells, absorbers for dye-sensitized solar cells, emitters for red and near infra-red organic light-emitting diodes (OLEDs), absorbers and re-emitters for organic concentrators (e.g., large area organic film for collection of sunlight) for small-size and high efficiency inorganic photovoltaics, and absorbers for hydrogeneration.
