POLYMERIZED 1,5-SUBSTITUTED TRIAZOLE, PREPARATION METHOD THEREFOR, AND USE THEREOF

WIPO Patent Application WO/2024/055383

A1

Disclosed are a polymerized 1,5-substituted triazole, a preparation method therefor, and the use thereof. A binary trimethylsilylacetylene monomer and a binary organic azide monomer are used as raw materials to react in the presence of potassium tert-butoxide and a polar aprotic solvent, so as to obtain the polymerized 1,5-substituted triazole. The polymerized 1,5-substituted triazole has the following structural general formula (I), n being an integer of 2-200, and R and R' being the same or different organic groups. The above synthesis method uses readily available raw materials, has mild reaction conditions, and does not need using a transition metal catalyst, thus eliminating the impact of residual transition metals on the photoelectric and biological properties of the polymer. In addition, the reaction has extensive applicability of substrates and good compatibility of functional groups, thereby allowing for the introduction of multiple functional groups. The prepared polymerized 1,5-substituted triazole has good processability, relatively high thermal stability and aggregation-induced light emission performance, thereby having potential application values in the fields of optical plastics, biomedical materials and fluorescence sensing, etc.
