An electrically conductive film suited to use as a transparent anode, a method of forming the film, and an electronic device comprising the film are disclosed. The device includes a conductive polymer electrode defining first and second surfaces and having an electrical conductivity gradient between the first and second surfaces. A second electrode is spaced from the second surface by at least one organic material layer, such as a light emitting layer.

Electrically conductive polymers

The present invention describes the use of red, green and, if necessary, blue dopants dispersed in a universal host material as the active emitting layer in OLEDs. The universal host is transparent in the visible region, and may be emissive in the blue region when used as the blue emitting species or possesses carrier transport properties. By dispersing the dopants in the universal host, efficient energy transfer from host to guest and/or direct carrier recombination on the dopant takes place resulting in bright red, green or blue emission, depending on the dopant. The resulting spectra are characteristic of the guest molecules.

The invention relates to the deposition of transparent conducting thin films, such as transparent conducting oxides (TCO) such as tin doped indium oxide (ITO) and aluminum doped zinc oxide (AZO) on flexible substrates by pulsed laser deposition. The coated substrates are used to construct low cost, lightweight, flexible displays based on organic light emitting diodes (OLEDs).

A method of patterning electrically conductive polymers is: forming a surface of a conducting polymer on a substrate, applying a mask to this surface, applying irradiation to form regions of exposed conducting polymer and regions of unexposed conducting polymer, removing the mask, and gently removing by non-chemically reactive means the regions of exposed conducting polymer.

Pentacene derivatives substituted with two or more aromatic, substituted aromatic, heteroaromatic, or substituted heteroaromatic groups are dopants for organic electroluminescent devices. When combined with host materials and incorporated into an organic light emitting devices, the pentacene derivatives are red emitters with narrow spectra.

Nonlinear optical composites with large third-order optical response compd of metal clusters uniformly dispersed in polymers are prepared by vapor deposition of a metal onto a cold support while simultaneously cocondensing a vapor of an organic material. Where the organic material is a monomer, it polymerizes either when it comes in contact of the metal and/or when the cold surface is warmed. The unpolymerized monomer is removed to yield a processable composite. When the organic material is a diluent, it deposits as a solid on the cold surface forming a dispersion of the solid metal clusters in the liquid diluent. A polymer solution is then mixed with the dispersion and the composite is formed after removal of the diluent and the solvent for the polymer.
