摘要:A method for a synthesis of a polymer containing multiple epoxy groups includes steps of: under protection of nitrogen or argon, with a photosensitive free radical initiator under an ultraviolet light irradiation, initiating a mixture of a dithiol compound and alkynyl glycidyl ether or other alkynyl-containing compounds to proceed a thiol-yne polymerization, so as to obtain the polymer. The number of the epoxy groups is able to be adjusted through changing a type of a dithiol monomer, a mixing ratio of the dithiol monomer, and a mixing ratio between the alkynyl glycidyl ether and other alkynyl compounds. The present invention has advantages of: fast reaction, convenient process, easy post-processing, a large number of the epoxy groups, and adjustable and controllable content. The obtained polymer has a wide potential application in fields of coating, adhesive, ink, encapsulating material, resin for composite material, additive, high performance material, function material, and so on.

摘要:Provided herein are methods for producing products containing strained carbocycles, such as cyclopropene moieties and/or bicyclobutane moieties. The methods include combining an alkyne and a carbene precursor in the presence of a heme protein, e.g., a cytochrome P450, under conditions sufficient to form the strained carbocycle. Reaction mixtures for producing strained carbocycles are also described, as well as whole-cell catalysts comprising heme proteins and variants thereof for forming cyclopropenes, bicyclobutanes, and related products.

摘要:The present disclosure provides methods of sequencing polynucleotides and compounds, compositions for sequencing of polynucleotides, and synthesis of such compositions. The chemical compounds include nucleotides and their analogs which possess a sugar moiety comprising a cleavable chemical group capping the 3′-OH group and a base, but without covalently bounded dye. The cleavable chemical group is reactive to form covalent bond(s) with a dye used to confirm the presence of the expected base-pairing. The cleavable chemical group capping the 3′OH group can be removed together with the covalently bounded dye. Furthermore, after the cleavable chemical group is cleaved, the free 3′-OH group can be active in continued elongation. Example chemical compounds according to the present disclosure are shown as Formulas (II) and (V):

摘要:In one aspect, the present invention is directed to dendrimers comprised of macromolecules and trifunctional branches. In another aspect, the invention relates to methods for generating dendrimeric compositions comprising macromolecules and trifunctional branches. In certain embodiments, the radial density of the dendrimeric composition is controlled by selective incorporation of branches.
