摘要: The high efficiency and fidelity of click chemistry permits a large number of diverse dendrimers encompassing a wide variety of functionalities at the chain ends, repeat units, and/or core to be prepared. Almost quantitative yields were obtained during the synthesis. In some cases, filtration or solvent extraction was the only method required for purification. These features represent a significant advancement in dendrimer chemistry and demonstrate an evolving synergy between organic chemistry and functional materials.

摘要: A copper catalyzed click chemistry ligation process is employed to bind azides and terminal acetylenes to provide 1,4-disubstituted 1,2,3-triazole triazoles. The process comprises contacting an organic azide and a terminal alkyne with a source of reactive Cu(I) ion for a time sufficient to form by cycloaddition a 1,4-disubstituted 1,2,3-triazole. The source of reactive Cu(I) ion can be, for example, a Cu(I) salt or copper metal. The process is preferably carried out in a solvent, such as an aqueous alcohol. Optionally, the process can be performed in a solvent that comprises a ligand for Cu(I) and an amine.

摘要: Adhesive polymers are formed when polyvalent azides and alkynes are assembled into crosslinked polymer networks by copper-catalyzed 1,3-dipolar cycloaddition. The condensation polymerization is efficiently promoted by Cu ions either leached from the metal surface or added to the monomer mixture, and strong interactions with metal surfaces are provided by the multiple triazole binding elements produced. The adhesive polymers may be formed either as adhesive polymer coatings or as adhesive polymer cement.

摘要: A metal catalyzed click chemistry ligation process is employed to bind azides and terminal acetylenes to give triazoles. In many instances, the reaction sequence regiospecifically ligates azides and terminal acetylenes to give only 1,4-disubstituted [1,2,3]-triazoles.
