Abstract

The invention discloses a hyperbranched polyphenyltriazole formate, a preparation method and application thereof. Using phenylpropiolic acid tribasic ester and binary organic azide monomer, in polar aprotic solvent, heating and reacting for a period of time to obtain hyperbranched polyphenyltriazole formic acid ester. The reaction raw materials in the present invention are easy to obtain, and no by-products are generated during the polymerization process, which conforms to atom economy. The substrate of the polymerization reaction has a wide range of applications, has good compatibility with functional groups, and can easily introduce functional groups. At the same time, no metal catalyst is used in the preparation process of the polymer, which avoids the impact of catalyst residue on the biological activity and photoelectric performance of the polymer. Because the polymer contains a tetraphenylethylene structure, the polymer has good aggregation-induced luminescent properties, and can be used as a chemical sensor to detect polynitroaromatic explosives with high sensitivity.

Description

technical field

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

[0002] Hyperbranched polymers are a class of macromolecules with three-dimensional structure and high branching, which have the characteristics of low viscosity, difficult to crystallize, good solubility, a large number of terminal functional groups and high reactivity. Due to their unique structure and properties, hyperbranched polymers have been widely used in coatings, additives, drug and catalyst carriers, optoelectronic materials and other fields. With the unremitting efforts of polymer chemists, more and more functional hyperbranched polymers have been synthesized. However, the preparation of these polymers often requires strict experimental conditions and the use of metal catalysts, and it is difficult to completely remove t...
