Abstract

The invention discloses a preparation method and application of a glycopolymer. According to the preparation method, the combination of active ester exchange and active free-radical polymerization reaction at room temperature is utilized for the first time to successfully prepare the glycopolymer with controllable molecular weight and narrower molecular weight distribution by a one-step one-pot process. The invention provides a simple effective way for synthesizing the glycopolymer. The application method comprises the following steps: dialyzing the glycopolymer, carrying out freeze-drying, mixing the freeze-dried glycopolymer with an AgNO3 solution, and preparing the fluorescent sugar-containing silver nano cluster by using the glycopolymer as a stabilizer. The method for preparing the glycopolymer is also applicable to the preparation of glucose, galactose and other glycopolymers.

Description

technical field [0001] The invention relates to a preparation method of a sugar-containing polymer, in particular to a preparation method of a sugar-containing polymer combined with active transesterification and living radical polymerization, and the application of the sugar-containing polymer. Background technique [0002] Sugar is the building block of many natural products in nature, is a common source of energy in living organisms, and plays a vital role in many biological processes. In recent years, the preparation of sugar-containing polymers from sugar-based monomers has become a research hotspot in the fields of chemistry and biology. Sugar-containing polymers refer to functional polymer materials formed by introducing sugar components into polymer molecular chains through different chemical reaction pathways. Due to the presence of sugar groups, this kind of polymer can improve the biocompatibility, hydrophilicity and biodegradability of the polymer, and has a goo...
