标题 :Synthesis and polymerization of vinyl triazolium ionic liquids
发明人：LUEBKE DAVID; NULWALA HUNAID; MATYJASZEWSKI KRZYSZTOF; ADZIMA BRIAN
权利人:US ENERGY; THE US DEPARTMENT OF ENERGY
摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

权利人:ALCHEMIA LTD
摘要:This invention relates to combinatorial libraries of potentially biologically active mainly monosaccharide compounds and to methods of preparing same. These compounds are variously functionalized, with a view to varying lipid solubility, size, function and other properties, with the particular aim of discovering a drug or drug-like compound, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of monosaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of amino acid and peptide side chain units of isosteres thereof.
