Abstract
Description
technical field
[0001] The invention relates to the fields of polymer chemistry and material science, in particular to a novel hyperbranched polytriazole formate and its preparation method and application. Background technique
[0002] In the 1960s, German chemist Rolf Huisgen first studied the 1,3-dipolar cycloaddition reaction of cyclic triazoles prepared from organic azide and alkyne compounds (Chem. Ber. 1967, 100, 2494). However, due to the slow reaction rate and the lack of stereoselectivity of the product, this reaction has not been widely used. In 2002, the Meldal and Sharpless research groups independently reported the monovalent copper salt catalyzed azide-alkynyl cycloaddition reaction, and found that the reaction rate was greatly accelerated, and the product was stereoselective, only generating 1,4-disubstituted 1,2,3-triazole compounds (J.Org.Chem.2002, 67, 3057, Angew.Chem., Int.Ed.2011, 40, 2004). Immediately, Sharpless et al named the reaction "click chemis...
