摘要:The in vitro polymerization of silica, silicone, non-silicon metalloid-oxane and metallo-oxane polymer networks, by combining a catalyst and a substrate to polymerize the substrate to form silica, polysiloxanes, polymetalloid-oxanes polymetallo-oxanes (metal oxides), polyorganometalloid oxanes, polyorganometallo oxanes, and the polyhydrido derivatives thereof, at about neutral pH. The nanostructure-directing catalysts have a nucleophilic functionality and a hydrogen-bonding acceptor group, and include: silicateins, enzymes that work by a mechanism functionally related to that of the silicateins; self-assembling peptides related to those synthesized and demonstrated capable of acting as biomimetic substitutes for the silicateins; non-peptide-based synthetic polymers containing a nucleophilic group and a hydrogen bonding amine such that the polymer functions by a mechanism of action related to that of the silicateins; materials having such chemical functionality as a nucleophilic group and or a hydrogen bonding amine which, acting in concert with nanoconfinement and or chemical functionality of the surface or matrix to which the functionality is attached, acts catalytically by a mechanism related to that of the silicateins; and small-molecule non-polymeric biomimetic catalysts that operate by the same mechanism as silicateins.

摘要:A method of forming a silsesquioxane/Q/siloxane polymer or oligomer system used to form coatings or monoliths, includes the step of mixing silsesquioxane, siloxane and alkoxysilane components having structures as presented below in ratios as presented below with a soluble F − catalyst and water in a suitable solvent so that on stirring at temperatures of −20° to approximately 100° C. all of the components dissolve producing a solution. A soluble oligomer is formed in equilibribum with single molecules with specific structures including [RSiO 1.5 ] x [R′MeSiO] y [R′Me 2 SiOSiO 1.5 ] z (where Râ•?R′ or R″ or R 1 or R 2 as denoted below) and where x, y and z are mole fractions whose sum is equal to one.

摘要:Anti-reflective coating materials for deep ultraviolet photolithography include one or more organic light-absorbing compounds incorporated into spin-on-glass materials. Suitable absorbing compounds are strongly absorbing over wavelength ranges around wavelengths such as 365 nm, 248 nm, and 193 nm that may be used in photolithography. A method of making absorbing spin-on-glass materials includes combining one or more organic absorbing compounds with alkoxysilane or halosilane reactants during synthesis of the spin-on-glass materials.
