- Preparation method of dendritic cationic polyion liquid
-
The invention discloses a preparation method of a dendritic cationic polyion liquid, and belongs to the technical field of high polymer materials, the method comprises the following steps: firstly synthesizing a polyfunctional compound with azide and tertiary amino as a monomer, then respectively carrying out a copper catalyzed azide-alkyne cycloaddition reaction (CuAAC) and a Menshutkin reaction on the monomer and brominated propyne to obtain the dendritic polyion liquid by adopting a gradual growth mode. The preparation method provided by the invention has the advantages of mild reaction conditions and high efficiency, the target product can be obtained only through simple precipitation in the post-reaction treatment method, and the operation is simple. The dendritic polyion liquid has potential application value in the fields of biological medicines, functional materials and the like.
