The present invention provides a heterocyclic compound and an organic light-emitting device including the heterocyclic compound. The organic light-emitting devices using the heterocyclic compounds have high-efficiency, low driving voltage, high luminance and long lifespan.

Organic light-emitting device

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

OLEDs doped with phosphorescent compounds

The present invention is an environmental barrier for an OLED. The environmental barrier has a foundation and a cover. Both the foundation and the cover have a top of three layers of (a) a first polymer layer, (b) a ceramic layer, and (c) a second polymer layer. The foundation and/or the cover may have a at least one set of intermediate barrier each having (a) an intermediate polymer layer with (b) an intermediate ceramic layer thereon. In a preferred embodiment, the foundation has a substrate upon which at least a top is deposited. An OLED is constructed upon the top, opposite the substrate. The cover of at least a top then placed over the OLED. The placement may be by gluing or preferably by vacuum deposition. For use as a display, it is preferred that either the ceramic layer(s) in the foundation, cover or both is substantially transparent to the light emitted by the OLED. Each layer of the foundation and the cover is preferably vacuum deposited. Vacuum deposition includes monolayer spreading under vacuum, plasma deposition, flash evaporation and combinations thereof. It is further preferred that all layers are deposited and cured between rolls or rollers to avoid the defects that may be caused by abrasion over a roll or roller.

Environmental barrier material for organic light emitting device and method of making

Provided is an organic electroluminescence device having high luminous efficiency, high heat resistance and an extremely long lifetime. The organic electroluminescence device of the present invention includes an organic thin film layer composed of one or more layers containing at least a light emitting layer is interposed between a cathode and an anode. The light emitting layer includes a compound containing a condensed ring and a luminescent metal complex capable of emitting light having a red-based color. It is preferable that the compound containing a condensed ring includes a host material, while the luminescent metal complex capable of emitting light having a red-based color includes a phosphorescent dopant.

Organic Electroluminescent Device

An organic light emitting device (OLED) is disclosed for which the hole transporting layer, the electron transporting layer and/or the emissive layer, if separately present, is comprised of a non-polymeric material. A method for preparing such OLED's using vacuum deposition techniques is further disclosed.

Vacuum deposited non polymeric flexible organic light emitting devices

Methods for preparing organic thin films on substrates, the method comprising the steps of providing a plurality of organic precursors in the vapor phase, and reacting the plurality or organic precursors at a sub-atmospheric pressure. Also included are thin films made by such a method and apparatuses used to conduct such a method. The method is well-suited to the formation of organic light emitting devices and other display-related technologies.

Low pressure vapor phase deposition of organic thin films

In a method using organic vapor phase deposition (OCPD), for the growth of thin films of optically nonlinear organic salts, a volatile precursor of each component of the salt is carried as a vapor to a hot-wall reaction chamber by independently controlled streams of carrier gas. The components react to form a polycrystalline thin film on substrates of glass and gold. Excess reactants and reaction products are purged from the system by the carrier gas. For example, the method provides the growth of polycrystalline, optically nonlinear thin films of 4'-dimethylamino-N-methyl-4-stilbazolium tosylate (DAST) with >95 % purity.

Luminescent compositions are described comprising lanthanide-containing nanoclusters comprising lanthanide atoms bonded to at least one semimetal or transition metal via an oxygen or sulfur atom. Novel compositions include an antenna ligand complexed with the nanoclusters. The rare earth-metal nanoclusters are in the size range of 1 to 100 nm. Articles, such as solar cells, are described in which the nanoclusters (with or without antenna ligands) are dispersed in a polymer matrix. Novel methods of making luminescent films are also described.

A method and apparatus for forming patterned coatings of thin film, non-polymeric compounds on a substrate. A mixture of the non-polymeric compound and a liquid carrier is pumped into the interior of a heated evaporation box having an internal temperature sufficient to convert substantially all of the non-polymeric compound and liquid carrier to a gaseous form. The non-polymeric compound and liquid carrier are then removed from the evaporation box via exit slit in the evaporation box. Adjacent to the exit slit, and maintained in a vacuum, is a first substrate upon which the non-polymeric compound condenses. The first substrate is in motion, for example on a web roller, thereby allowing a continuous coating of the non-polymeric compound to be applied to the first substrate. Once the non-polymeric compound is applied to one side of the first substrate, an energy source is then directed toward the opposite side of the first substrate. In this manner, a portion of the non-polymeric compound is removed from the first substrate. A second substrate is then provided adjacent to the first substrate, and the non-polymeric compound is thereby transferred from the first substrate onto the second substrate. By repeatedly transferring portions of the non-polymeric material from the first substrate to the second substrate in this manner, the thin film, non-polymeric materials can be formed onto the second substrate in a predetermined pattern, and in a continuous and highly efficient process.
