摘要:The present invention provides unimolecular metal complexes having increased activity in the copolymerization of carbon dioxide and epoxides. Also provided are methods of using such metal complexes in the synthesis of polymers. According to one aspect, the present invention provides metal complexes comprising an activating species with co-catalytic activity tethered to a multidentate ligand that is coordinated to the active metal center of the complex.

发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.

标题:Silsesquioxane polymers, method of synthesis, photoresist composition, and multilayer lithographic method

摘要:Novel silsesquioxane polymers are formed by methods which avoid the use of BBr 3 . The novel silsesquioxane polymers are especially useful in negative photoresist compositions and photolithographic processes. Alternatively, improved silsesquioxane polymer-containing negative photoresist compositions are obtained by using a polymer component containing a blend of silsesquioxane polymer and non-silsesquioxane polymer. The photoresist compositions provide improved dissolution characteristics enabling the use of 0.26N TMAH developer. The photoresist compositions also provide improved thermal characteristics enabling use of higher processing temperatures. The photoresist compositions are especially useful in a multilayer photolithographic processes and are capable of producing high resolution.

标 题:Biocompatible polymeric nanoparticles degrade and release cargo in response to biologically relevant levels of hydrogen peroxide
发明人：ALMUTAIRI ADAH; DE GRACIA LUX CAROLINE
权利人:UNIV CALIFORNIA
摘要:Disclosed are compositions and synthesis methods that pertain to biocompatible polymeric capsules capable of undergoing backbone degradation and cargo release upon exposure to biologically relevant concentrations of hydrogen peroxide (50-100 μM of H 2 O 2 ). In the invention, bio-responsive polyester bearing boronic ester triggers groups that degrade upon exposure to low concentrations of H 2 O 2 . The degradation is induced by transformation of a boronic ester to a phenol, which undergoes a quinone methide rearrangement to break down the polyester backbone.
