标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

摘要:A carborane-siloxane compound is provided having the repeat unit n nQ contains any of —SiR 2 —, —SiR 2 —O—, —C≡C—C≡C—, carboranyl, and U′. Each R and R′ is alkyl, aryl, alkylaryl, haloalkyl, haloaryl, or mixtures thereof. Each U′ is derivable from hydrosilation of an alkenyl or alkynyl group. Each T is alkyl, aryl, alkylaryl, haloalkyl, haloaryl mixtures thereof, —(O—SiR′ 2 ) x H, or the repeat unit. Each x and x′ is a positive integer. The compounds may be made be reacting a carborane-siloxane precursor having unsaturated end groups with a siloxane crosslinker in the presence of a hydrosilation catalyst.

摘要:A crosslinked polymer and process of making it are disclosed. A copolymer having at least one alkyne group, carborane group, and alkylsiloxane group is reacted with a siloxane crosslinker in a hydrosilation reaction. This produces a crosslinked polymer where the crosslink sites are reacted alkyne groups.

标题:Synthetic method for the synthesis of silicon polyether copolymers
发明人：CRIVELLO JAMES V; FAN MINGXIN

摘要:The present invention is based on the discovery that various metal catalysts will catalyze the ring opening polymerization of epoxides to yield polyethers. The present invention therefore provides a method of making a polymeric product by ring-opening polymerization of heterocyclic epoxide monomer including the steps of preparing a mixture comprised of a catalyst; a Si--H containing compound; and at least one compound which is a heterocyclic epoxide containing monomer; and reacting the mixture at a temperature effective to promote ring-opening polymerization of the at least one compound to produce a polymeric product, preferably at room temperature. n The present invention additionally provides for the silicone-polyether compositions created by this method.

摘要:A method of: providing a solution of: a dichloroaromatic compound having an electron-withdrawing group bound to each aromatic ring containing one of the chloride groups; an excess of a dihydroxyaromatic compound; a base; and a solvent; heating the solution to a temperature at which the dichloroaromatic compound and the dihydroxyaromatic compound react to form an aromatic ether oligomer; and reacting the aromatic ether oligomer with a chlorodialkylvinylsilane to form one or more vinyl-terminated compounds having the formula below. The aromatic ether oligomer is a dihydroxy-terminated compound or a dimetallic salt thereof. Water formed during the heating is concurrently distilled from the solution. Each R is an alkyl group, Ar 1 is a residue from the dichloroaromatic compound, Ar 2 is a residue from the dihydroxyaromatic compound, and n is a non-negative integer.
