20130214257 | CHARGE INJECTION AND TRANSPORT LAYERS - Compositions for use in hole transporting layers (HTLs) or hole injection layers (HILs) are provided, as well as methods of making the compositions and devices fabricated from the compositions. OLED devices can be made. The compositions comprise at least one conductive conjugated polymer, at least one semiconducting matrix component that is different from the conductive conjugated polymer, and an optional dopant, and are substantially free of an insulating matrix component. | 08-22-2013 |
20130334504 | ORGANIC LIGHT EMITTING DIODE LIGHTING DEVICES - An organic light emitting diode (OLED) device includes a substrate, an anode, a cathode, an active region including an organic material, wherein the active region is electrically coupled to the anode and the cathode, at least one coupler configured to electrically couple at least one of the anode or the cathode to a power supply, and an encapsulation that isolates the active region from an ambient environment. A lighting system can be made including a plurality of OLED devices. A lighting system can be assembled using the OLED devices from a kit. The OLED devices may be polymer light emitting diode (PLED) devices or small molecule light emitting diode (SMOLED) devices. The OLED devices can use regio-regular poly-thiophene. | 12-19-2013 |
20130344648 | HOLE TRANSPORT COMPOSITIONS AND RELATED DEVICES AND METHODS (II) - A composition comprising: at least one compound comprising a hole transporting core, wherein the core is covalently bonded to a first arylamine group and also covalently bonded to a second arylamine group different from the first, and wherein the compound is covalently bonded to at least one intractability group, wherein the intractability group is covalently bonded to the hole transporting core, the first arylamine group, the second arylamine group, or a combination thereof, and wherein the compound has a molecular weight of about 5,000 g/mole or less. Blended mixtures of arylamine compounds, including fluorene core compounds, can provide good film formation and stability when coated onto hole injection layers. Solution processing of OLEDs is a particularly important application. | 12-26-2013 |
20140054509 | SULFONATION OF CONDUCTING POLYMERS AND OLED, PHOTOVOLTAIC, AND ESD DEVICES - Conducting polymer systems for hole injection or transport layer applications including a composition comprising: a water soluble or water dispersible regioregular polythiophene comprising (i) at least one organic substituent, and (ii) at least one sulfonate substituent comprising sulfonate sulfur bonding directly to the polythiophene backbone. The polythiophene can be water soluble, water dispersible, or water swellable. They can be self-doped. The organic substituent can be an alkoxy substituent, or an alkyl substituent. OLED, PLED, SMOLED, PV, and ESD applications can be used. | 02-27-2014 |
