A near infrared phosphorescent organometallic complex includes a cyclometalating ligand and a transition metal. The cyclometalating ligand includes a fused aromatic ring structure with carbon atoms, and a heteronuclear aromatic ring with a nitrogen atom. The transition metal is bonded to the nitrogen atom in the heteronuclear aromatic ring and one of the carbon atoms in the fused aromatic ring structure. The heteronuclear ring can be part of the fused aromatic ring. The organometallic complex is capable of phosphorescent emission with maximum emission intensity occurring at a wavelength in a range from about 650 nm to about 2000 nm.

Organometallic materials for optical emission, optical absorption, and devices including organometallic materials

A method for fabricating organic light-emitting diodes (OLEDs) and OLED displays using screen-printing, where a first electrode, at least one organic material, and a second electrode are formed on a substrate and at least one of the first and second electrodes and the at least one organic material is screen printed by positioning a screen with openings forming a pattern above a substrate and depositing a material onto the substrate through the openings. Exemplary embodiments include fabricating the electrodes and/or the at least one organic material as continuous layers or uniform, discrete blocks on the substrate and fabricating red, green, and blue OLEDs on the same substrate, which are then placed in OLED displays.

Method for fabricating organic light-emitting diode and organic light-emitting display using screen-printing

The invention is directed to oxidized charge transport materials having hole transport capability in organic light emitting device (OLEDs). A charge transport compound including more than two triarylamine groups, or including at least one triarylamine group and at least one fluorene group, is partly complexed with an oxidant, such as a Lewis acid, preferably present in an amount between 0.2 and 20 percent by weight. The resulting charge transport materials exhibit good hole transport characteristics and film forming properties.

Semiconducting hole injection materials for organic light emitting devices

An organic device including an organic layer of organic material; and a cathode in contact with the organic layer and including a mixture of a metal and an insulator. The mixture can be an alloy or a composite of the metal and insulator, and can be for example a mixture of Al:LiF or Al:CsF. The device can be incorporated in an organic light-emitting device, an organic transistor, an organic solid state laser, or any device requiring carrier injection into an organic material.
