Abstract: The present invention is directed to simplified OLED structures comprising an anode layer, a hole injecting layer (HIL) in direct contact with the anode layer, an emissive organic electron transporting layer (ETL) in direct contact with the hole injecting layer, and a cathode layer in direct contact with the emissive organic electron transporting layer. The hole injecting material used in the hole injecting layer is characterized, in particular, as being an organic material having an ionization potential that is not more than about 0.7 eV greater than the ionization potential of the material used for the anode layer. The emissive organic electron transporting layer comprises an organic electron transporting material and an organic hole-trapping emissive material, for example, an organic phosphorescent material that produces emission from a triplet excited state of an organic molecule.

Abstract: Organic light emitting devices are described wherein the emissive layer comprises a host material containing an emissive molecule, which molecule is adapted to luminesce when a voltage is applied across the heterostructure, and the emissive molecule is selected from the group of phosphorescent organometallic complexes, including cyclometallated platinum, iridium and osmium complexes. The organic light emitting devices optionally contain an exciton blocking layer. Furthermore, improved electroluminescent efficiency in organic light emitting devices is obtained with an emitter layer comprising organometallic complexes of transition metals of formula L2MX, wherein L and X are distinct bidentate ligands. Compounds of this formula can be synthesized more facilely than in previous approaches and synthetic options allow insertion of fluorescent molecules into a phosphorescent complex, ligands to fine tune the color of emission, and ligands to trap carriers.

Abstract: Method for making a patterned thin film of an organic semiconductor. The method includes condensing a resist gas into a solid film onto a substrate cooled to a temperature below the condensation point of the resist gas. The condensed solid film is heated selectively with a patterned stamp to cause local direct sublimation from solid to vapor of selected portions of the solid film thereby creating a patterned resist film. An organic semiconductor film is coated on the patterned resist film and the patterned resist film is heated to cause it to sublime away and to lift off because of the phase change.
