Abstract

The invention provides a two-component hydrogen bond eutectic compound and a preparation method and application thereof, and belongs to the technical field of material synthesis. The chemical formulaof the two-component hydrogen bond eutectic compound is (C2N3H2)<+>(HC4O4)<->, and triazole and squaric acid are connected through N-H...O hydrogen bonds. The squaric acid and the triazole are taken as reaction substrates, under the condition of the optimal molar ratio, methyl alcohol is taken as a solvent, mixing and crystallization are carried out, and the two-component hydrogen bond eutectic compound with the chemical formula of (C2N3H2)<+>(HC4O4)<-> is formed, wherein the squaric acid and the triazole are stably connected through the N-H...O hydrogen bonds, through measurement, the conductivity of the two-component hydrogen bond eutectic compound is 8.9*10<-8> S / cm (30 DEG C), a three-dimensional hydrogen bond network structure is honeycomb-like, the thermal decomposition temperature reaches up to 182 DEG C, and the two-component hydrogen bond eutectic compound can be used as a potential proton conductive material to replace a traditional expensive perfluorosulfonic acid membrane.The two-component hydrogen bond eutectic compound has the advantages that the preparation method is simple, the cost is low, the repeatability is good, the yield reaches up to 95% or above, and the popularization and application prospects are wide.

Description

technical field [0001] The invention belongs to the technical field of material synthesis, and in particular relates to a two-component hydrogen bond eutectic compound and its preparation method and application. Background technique [0002] Proton-conducting and proton-conducting materials play an increasingly important role in batteries, electrochemical sensors, water / steam electrolysis, and biological systems. Traditional proton-conducting materials are mainly represented by perfluorosulfonic acid membranes, but they are expensive and have potential fluorine risks. New low-cost, fluorine-free polymer proton exchange membranes are developed to replace traditional high-priced perfluorosulfonic acid membranes. Sulfonic acid membrane is a research hotspot in the field of proton-conducting materials. [0003] Hydrogen-bonded proton-conducting materials are a type of ion groups or molecules connected by hydrogen bonds to form a chain or framework structure. Under the conditio...
