Problems solved by technology

Although many scientific researchers have developed many organic reaction systems for oxidation with oxygen, there are still many problems, such as: harsh reaction conditions (requires high temperature and high pressure environment), limited applicability of the reaction, and difficult synthesis of reaction substrates, etc. etc., which limits the development of oxygen oxidation system
Currently, there are no reports of oxygen participating in the oxidation and participating in the polymerization reaction to form the product

Abstract

The invention belongs to the technical field of organic synthesis and discloses a polyfuran compound and a preparation method thereof. The polyfuran compound has a structural general formula shown as a formula (I). The preparation method includes: in a normal-pressure oxygen environment, enabling bifunctional aryl acetylene monomer and oxygen to be in polymerization reaction in an organic solvent through joint action of a catalyst and a cocatalyst; dissolving a product in the organic solvent; adding into methanol for precipitation; collecting precipitate; drying to constant weight to obtain the polyfuran compound. The preparation method is conducted in the normal-pressure oxygen environment, and oxygen participates in formation of polymer, so that feeding proportion of the monomer does not need to be controlled; the polyfuran compound has high thermostability and excellent processability and has huge application prospect in the field of explosive detection and two-photo absorption due to special photophysical properties.

Description

technical field [0001] The invention belongs to the technical field of organic synthesis, and in particular relates to a polyfuran compound and a preparation method thereof. Background technique [0002] The development of new polymerization reactions is of great importance to polymer materials science. Alkynes are one of the chemical raw materials that are easy to obtain or synthesize. The use of alkynes to construct functional polymers has important academic and technical significance, and has attracted widespread attention from scientists. [0003] Oxidation reactions are a very important class of reactions in organic reactions and play an important role in functional group conversion. Although many researchers have developed some new oxidation methods in recent years, the field of chemistry is still facing great challenges in "how to use green oxidation reagents" and "how to achieve maximum atom economy". Traditional oxidants, such as: potassium permanganate, hydrogen ...
