标题:Use of functionalized onium salts as a soluble support for organic synthesis
发明人：VAULTIER MICHEL; GMOUH SAID; HASSINE FATIMA
权利人:CENTRE NAT RECH SCIENT; UNIV RENNES
摘要:The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A₁⁺, X₁^-, wherein A₁⁺ represents a cation and X₁^- represents an anion.

标 题:Synthesis and use of polymers containing integral binding-pair members

摘要:Conjugate monomers, polymers, and methods for the de novo synthesis of the polymers are provided. Conjugate organic monomers contain binding-pair members which upon polymerization become integrally associated with the resultant polymer. Specifically, antigens, antibodies, receptors, and ligands may be bound to organic monomers either directly by chemical reaction or indirectly by chemical spacer arms, and these conjugates may be polymerized or copolymerized with nonderivatized monomers to form polymers containing variable amounts of the binding-pair members. Such conjugate monomers and polymers find a wide variety of uses in binding to their binding-pair-member cognate which include selective removal of complementary binding-pair members from solution as well as in immunoassay procedures and in immunization regimes.

摘要:Semiconductor materials offer several potential benefits as active elements in the development of harvesting-energy conversion technologies. In particular, lead selenide (PbSe) semiconductors have been used and proposed to design solar energy harvesting devices, IR sensors, FET devices, amongst others. The present disclosure provides a simple, low cost synthesis of lead selenide using benzoic acid as the capping ligand in an opened environment. The use of an aromatic ligand, and mores specifically benzoic acid, provides robustness and more durability to the lead selenide, and therefore prevents the lead selenide from breaking or cracking easily. Also the aromatic ligand prevents the degradation and oxidation of the lead selenide, without affecting any of the lead selenide electronic and chemical characteristics.

标题:Use of tristyrylphenol alkoxylate sulfosuccinates in emulsion polymerization and coatings

摘要:Disclosed are the use of novel surfactants for the synthesis of emulsion polymer latexes, particularly those used in paints, coatings, and pressure sensitive adhesives. The surfactant compositions for emulsion polymer latexes comprise sterically bulky surfactants whose composition comprises at least one alkoxylated polyaryl substituted aromatic sulfosuccinate compound. The novel surfactants provide for the production of stable, small particle size distribution emulsion polymer latexes. The resulting latexes, when formulated into latex paint, impart improvements in water resistance as measured by film opacity, blister resistance and improved leveling characteristics, and when formulated into pressure sensitive adhesives, provide improved water resistance characteristics as measured by film opacity.

权利人:GILEAD SCIENCES
摘要:The present invention describes methods for the production of oligonucleotides under conditions which exploit the desirable characteristics, such as the property of sustaining high degrees of substitution, of functionalized organic polymeric supports while avoiding the sluggish kinetics and low rates of conversion which normally plague syntheses involving such solid supports. By employing the methods and materials disclosed, functionalized support, substituted to a degree of about 250 μmol/g, can be utilized at greater than 98% conversion levels for each sequential nucleotide coupling cycle, to provide unprecedented amounts of isolated oligonucleotide per gram of solid support.
