  • Patent number: 7205373
    Abstract: Methods for forming organosilicon esters and amides are provided. Additionally, organosilicon esters and amides are provided. The organosilicon esters and amides may be formed by contacting a hydrolase enzyme with an organosilicon reactant and an organic reactant. The enzyme may catalyze the formation of an ester bond between carboxylic acid, ester, or amide functional groups of the organosilicon or organic reactant and alcohol functional groups of the organic or organosilicon reactant. The enzyme may catalyze the formation of an amide bond between carboxylic acid, ester, or amide functional groups of the organosilicon or organic reactant and amine functional groups of the organic or organosilicon reactant.

  • Patent number: 7195924
    Abstract: Provided is a method for immobilizing a biomolecule on a solid substrate. The method includes coating the solid substrate with silane anhydride to introduce an anhydride functional group onto a surface of the solid substrate; obtaining a carboxyl group from the anhydride functional group by hydrolysis; reacting the carboxyl group with carbodiimide and succinimide to activate the carboxyl group; and contacting the biomolecule with the solid substrate having the activated carboxyl group on its surface to immobilize the biomolecule on the solid substrate.

  • Patent number: 7141692
    Abstract: A nonpolymeric silsesquioxane is provided wherein at least one silicon atom of the silsesquioxane is directly or indirectly bound to an acid-cleavable substituent RCL. The silsesquioxane has a glass transition temperature Tg of greater than 50° C., and the RCL substituent can be cleaved from the silsesquioxane at a temperature below Tg, generally at least 5° C. below Tg. The remainder of the silicon atoms within the silsesquioxane structure may be bound to additional acid-cleavable groups, acid-inert polar groups RP, and/or acid-inert nonpolar groups RNP. The nonpolymeric silsesquioxane can be a polyhedral silsesquioxane optionally having one to three open vertices, such that the polyhedron appears to be a “partial cage” structure, or a macromer of two to four such polyhedral silsesquioxanes. Photoresist compositions containing the novel nonpolymeric silsesquioxanes are also provided, as is a method for using the compositions in preparing a patterned substrate.

  • Patent number: 6930194
    Abstract: Siloxane bischloroformates are prepared in a continuous process by phosgenating siloxane bisphenols in a flow reactor using a substantial excess of phosgene and sodium hydroxide. While very high levels (>95%) of conversion of the siloxane bisphenol to the corresponding siloxane bischloroformate are achieved using a flow reactor according to the method of the invention, only more modest conversion (˜90%) of the siloxane bisphenol to the corresponding siloxane bischloroformate is attained when analogous batch processes are employed. The process holds promise for use in the manufacture of silicone-containing copolycarbonates which requires high purity siloxane bischloroformate intermediates.
