  • Patent number: 8057849
    Abstract: A method of forming conductive features on a substrate, the method includes reacting a metal compound with a reducing agent in the presence of a stabilizer in a reaction mixture comprising the metal compound, the reducing agent, and the stabilizer, wherein the reaction mixture is substantially free of solvent, to form a plurality of metal nanoparticles with molecules of the stabilizer on the surface of the metal nanoparticles. After isolating the plurality of metal nanoparticles, a liquid composition that includes a polymeric binder, a liquid and the plurality of metal nanoparticles with molecules of the stabilizer on the surface of the metal nanoparticles is deposited on a substrate by a liquid deposition technique to form a deposited composition. The deposited composition is then heated to form conductive features on the substrate.
    Type: Grant

  • Publication number: 20110003966
    Abstract: This invention relates to novel photochromic and electrochromic monomers and polymers based on 1,2-dithienylcyclopentene derivatives and method of using and synthesizing same. The compounds are reversibly interconvertible between different isomeric forms under suitable photochromic or electrochromic conditions. The electrochromic conversion may be catalytic. The application also relates to ultra-high density homopolymers prepared using ring-opening methathesis polymerization (ROMP) where the central ring of the 1,2-bis(3-thienyl)-cyclopentene is incorporated directly into the polymer backbone. The monomer units may be readily functionalized to enable the synthesis of polymers with diverse structural and electronic properties.
