Abstract

The invention discloses polyvinyl thioether ester as well as a preparation method and application thereof. The polyvinyl thioether ester is obtained through solution polymerization reaction by takinga binary acetylene acid ester internal alkyne monomer and a binary sulfydryl monomer as raw materials. The reaction raw materials are easy to obtain, no by-product is generated in the polymerization reaction process, and the atom economy is met; the polymerization reaction has wide substrate applicability and good functional group compatibility, and various functional groups can be conveniently introduced; no catalyst is used in the polymerization reaction, so that the influence of catalyst residues on photoelectric and biological properties of the polymer material can be eliminated. The polyvinyl thioether ester prepared by the invention has good processability, high thermal stability and aggregation-induced emission performance, and has application value in the aspects of optical plastics, biomedical materials, fluorescence sensing and the like.

Description

technical field

[0001] The invention belongs to the fields of polymer chemistry and material science, and in particular relates to a polyvinyl sulfide ester and a preparation method and application thereof. Background technique

[0002] The preparation of polymers with new structures based on new polymerization reactions has important research significance and application value. Among them, the polymerization of alkyne monomers to construct functional polymers has become a research hotspot in recent years. The reaction of alkynes with thiols was reported as early as the early 19th century, but did not attract much attention at the time. In 2009, Bowman and others in the United States used ultraviolet light to trigger the reaction of terminal alkyne and sulfhydryl group, that is, one alkyne group added two mercapto groups, and prepared a cross-linked polysulfide; in 2010, the Tang research group of Hong Kong University of Science and Technology used organic Base-catalyzed p...
