Abstract: Cross-linkable hole transport polymers comprising at least one first monomer comprised of an arylamine and at least one second monomer comprised of a fluorene, carbazole, diphenylsilicon or fused heterocyclic derivative are provided. In some embodiments, the hole transport polymers also comprise at least one third monomer, different from the second monomer, and comprised of a fluorene, carbazole, diphenylsilicon or fused heterocyclic derivative. Electronic devices made with the polymeric materials are also provided.

Abstract: An electronic device includes a radiation-emitting component, a radiation-responsive component, or a combination thereof. In one embodiment, the electronic device includes a substrate and a first structure overlying the substrate. The electronic device also includes a second structure that includes a first layer, wherein the first layer has a first refractive index, and the first layer includes a first edge. The electronic device further includes a second layer overlying at least portions of the first structure and the second structure at the first edge. The second layer has a second refractive index that is lower than the first refractive index. In another embodiment, the first structure includes a layer having a perimeter and a pattern lying within the perimeter. The pattern extends at least partly though the first layer to define an opening with a first edge. In another embodiment, a process is used to form the electronic device.

Abstract: A device having at least one layer including poly(p-phenylene)s based on 3,6-conjugated and 2,7-conjugated phenanthrene moietie having been synthesized by polycondensation using Ni(O)-mediated Yamamoto-type cross coupling are described as the charge transport layer or as the host for a dopant.

Abstract: There are provided electrically conducting polymer compositions comprising an electrically conductive polymer or copolymer and an organic solvent wettable fluorinated acid polymer. Electrically conductive polymer materials are derived from thiophene, pyrrole, aniline and polycyclic heteroaromatic precursor monomers. Non-conductive polymers derived from alkenyl, alkynyl, arylene, and heteroarylene precursor monomers. The organic-solvent wettable fluorinated acid polymer is fluorinated or highly fluorinated and may be colloid-forming. Acidic groups include carboxylic acid groups, sulfonic acid groups, sulfonimide groups, phosphoric acid groups, phosphonic acid groups, and combinations thereof. The compositions can be used in organic electronic devices.

Abstract: The invention provides novel pentaphenylene copolymers which are useful in electronic devices.
