标题:Synthesis of highly fluorinated amines for use in polymers and biomaterials
发明人：WILLIAMS TRAVIS J; BOZ EMINE
权利人:WILLIAMS TRAVIS J; BOZ EMINE; UNIV SOUTHERN CALIFORNIA
摘要:A method for forming a fluorinated compound includes a step of forming a sulfonate ester of a polyethylene glycol. The sulfonate ester is then reacted with a fluorinated diol in the presence of a base such that the polyethylene glycol is attached to one of the hydroxyl groups in the fluorinated diol. The other hydroxyl group in the fluorinated diol is reacted is converted into a leaving group and reacted with an number of nucleophiles. Complexes of the fluorinated compounds that as useful in Magnetic Resonance Imaging are also provided.

标题:Synthesis of thioether containing trialkoxysilanes

摘要:The invention relates to a radical-initiated thiol-ene or thiol-yne “clickâ€? reaction that provides a simple and efficient route to diverse trialkoxysilanes. Trialkoxysilanes made in this way are obtained in quantitative to near-quantitative yields with high purity without any or minimal purification. A wide range of functional groups is tolerated in this approach, and even complex alkenes click with the silane precursors. The modular nature of these radical-based thiol-ene or thiol-yne “clickâ€? reactions allows a wide variety of pendant groups to be coupled to silane compounds that can then be coupled to a wide variety surfaces in order to modify their material properties. Consequently, such radical initiated thiol-ene and thiol-yne reactions provide facile and efficient methods for preparing an enormous number of surface-active functional trialkoxysilanes.

摘要:The invention relates to a method for the preparation of a coating comprising at least one coating layer on a substrate, the method comprising the steps of a. providing monomers of the type R—(N) x -(L) m -(Câ•?C) n -(L′) o -(N′) y —R′, wherein R is a head moiety, R′ is a tail moiety, (C≡C) n is an oligoyne moiety, L and L′ are linker moieties, N and N′ independently are branched or unbranched optionally substituted C 1 -C 25 alkyl moieties optionally containing 1 to 5 heteroatoms, x, m, o, and y are independently 0 or 1, n is 4 to 12, and wherein the head moiety allows for an interaction with the surface of the substrate; b. bringing the monomers into contact with the substrate wherein the interaction of the head moieties of the monomers with the surface of the substrate induces at least a part of the monomers to align in a defined manner thereby forming a film on the surface and bringing the oligoyne moieties of the monomers into close contact with each other; c. inducing a reaction between oligoyne moieties by providing an external stimulus so as to at least partially cross-link the aligned monomers, thereby forming a coating layer on the substrate. The invention further relates to a coating obtainable according to the method of the invention, the use of a coating obtainable according to the method of the invention, a substrate comprising a coating obtainable according to the invention and the use of solid substrate. The invention further relates to a method for the synthesis ofthe monomers according to the invention.
