Patent number: 8674142Abstract: The invention relates to the use of polycyclic aromatic hydrocarbons (PAHs) such as naphthalene and its alkyl, aryl, or heteroatom substituted analogs, that act as catalysts in the presence of an alkali metal (Li, K, Na) for the reduction of electron-deficient and electron-rich triaryl phosphines to their corresponding alkali metal diaryl phosphide salts. The process is also useful for the catalysis of triaryl phosphine chalcogen adducts such as the sulfides, oxides, and selenides, diaryl(halo)phosphines, triaryl phosphine-borane adducts, and tetra-aryl bis(phosphines) that can also be reduced to their corresponding alkali metal diaryl phosphide salts. The invention also relates to small molecule PAHs and polymer tethered PAHs naphthenics.Type: GrantFiled: March 11, 2010Date of Patent: March 18, 2014Assignee: PMC Organometallix, Inc.Inventors: Nicholas J. Rodak, Gary S. Silverman, Stephen W. Carson

Publication number: 20120126273Abstract: A light-emitting devices and methods for forming light-emitting devices are provided. The device comprises of a substrate having a first refractive index, a transparent electrode that is coupled to an organic layer, where the transparent electrode has a second refractive index different from the first refractive index. An undercoat layer is selected that has a third refractive index to substantially match the first refractive index to the second refractive index. The undercoat layer is selected such that it has a capacity to reduce root mean square roughness of the transparent electrode film deposited. The undercoat layer is selected to improve electrical properties of the transparent electrode layer. The undercoat layer is provided between the substrate and the transparent electrode.Type: ApplicationFiled: July 1, 2010Publication date: May 24, 2012Applicant: Arkema Inc.Inventors: Roman Y.
