摘要:A method for hydrolyzing chlorosilanes having at least three chlorine atoms bonded to each silicon atom to form silicone resins. The method comprises adding at least one of hydridotrichlorosilane, tetrachlorosilane, or organotrichlorosilane to a two-phase mixture comprising a non-polar organic solvent, an aqueous phase comprising 0 to about 43 weight percent hydrochloric acid, and a surface active compound selected from the group consisting of organosulfates described by formula R2SO4H and alkali metal salts thereof, where R2 is selected from the group consisting of alkyl groups comprising about 4 to 16 carbon atoms and alkylphenyl groups comprising 7 to about 22 carbon atoms.

摘要:The present disclosure generally relates to self-assembly methods for generating porphyrin nanostructures. For example, in one embodiment a method is provided that includes preparing a porphyrin solution and a surfactant solution. The porphyrin solution is then mixed with the surfactant solution at a concentration sufficient for confinement of the porphyrin molecules by the surfactant molecules. In some embodiments, the concentration of the surfactant is at or above its critical micelle concentration (CMC), which allows the surfactant to template the growth of the nanostructure over time. The size and morphology of the nanostructures may be affected by the type of porphyrin molecules used, the type of surfactant used, the concentration of the porphyrin and surfactant the pH of the mixture of the solutions, and the order of adding the reagents to the mixture, to name a few variables.
