Publication number: 20130345412Abstract: The invention relates to a radical-initiated thiol-ene or thiol-yne “click” reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “click” reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.Type: ApplicationFiled: March 22, 2012Publication date: December 26, 2013Applicant: The Regents of the University of CaliforniaInventors: Robin L.

Publication number: 20130135838Abstract: The present invention provides an anisotropic conductive material in which lower continuity resistance and higher adhesive strength are obtained, and a method for manufacturing the same. When a glass substrate and a metal wiring material are thermally compressed and bonded, in an interface between the glass substrate and an anisotropic conductive material, Si on a surface of the glass substrate reacts on an alkoxyl group (OR) at an end of disulfide silane modified by hydrophobic silica, and chemically binds thereto. Furthermore, at an interface between the metal wiring material and the anisotropic conductive material, a part of S—S bonds (disulfide bonds) in disulfide silane dissociates due to the heat at the time of thermocompression bonding, and the dissociated sulfide silane chemically binds to metal Me.Type: ApplicationFiled: November 30, 2011Publication date: May 30, 2013Applicant: DEXERIALS CORPORATIONInventors: Reiji Tsukao, Tomoyuki Ishimatsu, Hiroki Ozeki
